Understanding Shopify's Liquid and Image CDN

What is Liquid in Shopify?

Let's start with the basics. Liquid is an open-source template language used by Shopify. It serves as a bridge between your store data and HTML, allowing you to insert dynamic content directly into your pages. This dynamic content isn't hard-coded into the page but is pulled from a database, meaning it can change from page to page based on specific criteria (source: First Pier).

This flexibility is what makes Shopify's Liquid so powerful. Whether it's product details, customer reviews, or personalized recommendations, you can use Liquid to create a tailored shopping experience for each visitor to your store. Beyond dynamic content, Shopify Liquid also plays a critical role in crafting custom storefronts, marketplaces, and APIs.

As Steve Pogson, our expert at First Pier, explains, "The flexibility of the Liquid code allows you to alter design elements and add functionality that your theme might not initially include. This enables you to create a unique and distinctive online presence, aligning your storefront with your brand identity and values."

How Shopify's Image CDN Works

Now, let's dive into Shopify's Image CDN. A Content Delivery Network (CDN) is a tool that Shopify uses to optimize your store's speed. It's a network of servers distributed worldwide, storing copies of your site's content. When a user visits your site, the CDN ensures that the content is loaded from the server closest to the user's physical location, reducing the time it takes for your site to load.

Shopify utilizes the Fastly CDN, a high-performing and reliable content delivery network. Fastly's CDN ensures that your store loads quickly, regardless of where your customers are located. This global coverage is critical for international e-commerce businesses, ensuring that all customers enjoy a fast and seamless shopping experience (source: First Pier).

In the context of Shopify image tagging, this means that your product images load faster, providing a smoother user experience and reducing the chance of potential customers leaving your site due to slow loading times.

Understanding how Shopify's Liquid and Image CDN work is crucial in mastering Shopify image tagging. In the following sections, we'll delve deeper into how you can leverage these tools to optimize your e-commerce store.

How to Use the Image_Tag Filter in Liquid

Basics of Image_Tag Filter

After getting a grasp of Shopify's Liquid and Image CDN, it's time to dive into the heart of Shopify image tagging. Let's start with the basics of the image_tag filter.

In Shopify Liquid, the image_tag filter is a powerful tool that generates an img element for an image URL. It's a straightforward way to create an img element with a src attribute linked to your desired image. For instance, to add an image to your site, you would use the following syntax:

liquid {{ 'logo.png' | asset_url | img_tag: 'Your Store Name' }}

This code will generate an img tag with the src attribute linked to the logo.png image and the alt attribute set as 'Your Store Name'. The alt attribute is essential for accessibility and SEO, as it provides a text description of the image for screen readers and search engines.

Generating Responsive Images with Image_Tag

It's vital to ensure that your website images are responsive and display correctly across all device sizes. This is where the image_tag filter truly shines. By generating responsive images, you can optimize your site for various screen resolutions, enhancing user experience and potentially boosting your SEO rankings.

The image_tag filter allows you to specify different image sizes using the srcset attribute. This attribute tells the browser the size of the image file at different viewport widths, enabling it to pick the most appropriate image size for the user's device.

To generate a responsive image with image_tag, you can use Shopify's img_url filter to create different image sizes. Take a look at the following example:

liquid {% assign image_sizes = '300x, 600x, 1200x' | split: ', ' %} <img src="{{ 'logo.png' | asset_url: '1x1' }}" alt="Your Store Name" srcset="{% for size in image_sizes %}{{ 'logo.png' | asset_url: size }} {{ size | remove: 'x' }}w{% unless forloop.last %}, {% endunless %}{% endfor %}">

In this snippet, we define three different sizes for the logo.png image: 300px, 600px, and 1200px. The srcset attribute then lists these image URLs along with their widths (denoted by w), allowing the browser to choose the best image based on the current viewport width.

Shopify Liquid, as our expert Steve Pogson emphasizes, can transform your e-commerce business by helping you create dynamic, customized, and highly engaging online stores. By mastering the use of the image_tag filter, you are one step closer to achieving this.

In the next section, we'll delve further into how you can customize image attributes with the image_tag filter, opening up a world of possibilities for your Shopify store.

Customizing Image Attributes with Image_Tag

Mastering the shopify image tag goes beyond just integrating it into your Shopify store. It's about understanding how to manipulate it to achieve your desired results. Our expert, Steve Pogson, emphasizes that the image_tag filter in Shopify allows you to customize image attributes, enhancing your store's visual appeal and performance.

Setting Width and Height Attributes

The first step in customizing image attributes is setting the width and height. By defining these attributes, you can control the display size of your images. This is crucial in ensuring your images look great on all devices, from desktop computers to mobile phones.

In Shopify's Liquid code, you can define the width and height attributes directly in the image_tag filter. Below is an example:

liquid {{ section.settings.image | image_url: '600x' | image_tag: width: 600, height: 785 }} In this example, the image width is set to 600 pixels, and the height is 785 pixels. The image_url filter is used to generate the image URL, and the image_tag filter is used to generate the complete HTML img tag with the specified width and height attributes.

Adding Srcset for Custom Widths

Next, let's talk about the srcset attribute. This attribute allows the browser to choose the most suitable image source based on the current viewport width and the resolution of the screen.

In the image_tag filter, you can define multiple image sources with different widths using the widths option. This is how it’s done:

liquid {{ section.settings.image | image_url: '600x' | image_tag: widths: '300, 600' }} In this example, two image sources are defined: one for screens with a width of 300 pixels and another for screens with a width of 600 pixels.

Using Sizes Attribute for Display Width

The sizes attribute complements the srcset attribute by telling the browser how wide the image will be displayed at different viewport sizes. This helps the browser make a better decision when choosing an image source from the srcset.

You can add the sizes attribute directly in the image_tag filter, as shown below:

liquid {{ section.settings.image | image_url: '600x' | image_tag: sizes: '(min-width: 400px) 600px, 100vw' }} In this example, the image will be displayed at 600 pixels wide for viewports that are at least 400 pixels wide. For smaller viewports, the image will take up the full width of the viewport (100vw).

At First Pier, we believe that mastering these customization techniques is critical to optimizing your Shopify store's visual appeal and performance. In the next section, we'll explore more advanced techniques for Shopify image tagging, including using the picture tag for art direction and fixing oversized mobile images with x-descriptors.

Advanced Image Tagging Techniques in Shopify

Moving forward in our journey to conquer Shopify image tagging, we're now ready to dive into some advanced techniques. As we often say here at First Pier, "The devil is in the details, and in e-commerce, these details are usually about images." So, let's explore these finer details and continue optimizing our Shopify store.

Using the Picture Tag for Art Direction

In Shopify, the picture tag is an incredibly useful tool for art direction. This tag allows us to serve different images to different devices, based on screen size and resolution. This means we can display a detailed, high-resolution image on a desktop, and a simpler, lower-resolution version on a mobile device, ensuring optimal user experience across all platforms.

To use the picture tag in Shopify, you'll need to utilize the img_url filter within the source element, specifying the desired image dimensions. For example:

<picture> <source media="(min-width: 800px)" srcset="{{ product.featured_image | img_url: '800x' }}"> <img src="{{ product.featured_image | img_url: '400x' }}" alt="{{ product.title }}"> </picture>

Here, a larger image is served to devices with a screen width of 800px or more, while a smaller image is displayed for smaller screens.

Fixing Oversized Mobile Images with X-Descriptors

Another advanced technique involves fixing oversized mobile images using x-descriptors. This method helps optimize the loading times on mobile devices, a crucial factor in improving user experience and SEO.

The x-descriptor specifies the pixel density of the device, allowing the browser to choose the most suitable image. To use x-descriptors in Shopify, simply add a multiplier (1x, 2x, 3x, etc.) after the image URL in the srcset attribute. For example:

<img src="{{ product.featured_image | img_url: '400x' }}" srcset="{{ product.featured_image | img_url: '400x' }} 1x, {{ product.featured_image | img_url: '800x' }} 2x" alt="{{ product.title }}">

Here, a high-resolution image is loaded for devices with a high pixel density (2x), and a lower-resolution image is used for standard devices (1x).

Adjusting Image Size with CSS

Finally, CSS can be an invaluable tool for controlling the display size of your images in Shopify. By defining the width and height properties in your CSS, you can ensure your images are displayed at the correct size, regardless of the resolution of the original image.

For instance, you could define a class for product images and set a specific width and height:

.product-image { width: 400px; height: 400px; }

Then, add this class to your Shopify image tag:

<img src="{{ product.featured_image | img_url: '400x' }}" class="product-image" alt="{{ product.title }}">

This ensures that your product images are displayed consistently across your Shopify store.

Mastering these techniques in Shopify image tagging can significantly improve your site's performance and user experience. By leveraging the picture tag for art direction, using x-descriptors to optimize mobile images, and controlling image size with CSS, you can ensure your Shopify store is visually appealing, fast, and efficient. As we like to say at First Pier, it's all about making your store work smarter, not harder!

Common Issues and Solutions in Shopify Image Tagging

Even with the best intentions, you might encounter issues when trying to optimize your Shopify image tags. But don't fret. At First Pier, we've tackled these roadblocks before and have solutions at the ready. Let's delve into some of the most common issues and their solutions.

Dealing with Missing Width and Height Attributes

One of the frequent issues Shopify users face is missing width and height attributes in their image tags. These attributes are essential as they inform the browser of the space that the image will occupy on the page, preventing layout shifts and enhancing your website's overall performance.

Consider this piece of code from our Shopify community:

html <img class="image-content__image" loading="lazy" src="{{ block.settings.image_2 | img_url: '300x300' }}" data-src="{{ img_url }}" data-widths="[180, 360, 540, 720, 900, 1080, 1296, 1512, 1728, 1944, 2048]" data-aspectratio="{{ block.settings.image_2.aspect_ratio }}" data-sizes="auto" alt="{{ block.settings.image_2.alt | escape }}">

If you notice, the width and height attributes are missing. A quick fix would be to add width and height attributes to the img tag, using the respective values for your image. For instance, if your image is 300x300 pixels, your updated code would look like this:

html <img class="image-content__image" loading="lazy" src="{{ block.settings.image_2 | img_url: '300x300' }}" width="300" height="300" data-src="{{ img_url }}" data-widths="[180, 360, 540, 720, 900, 1080, 1296, 1512, 1728, 1944, 2048]" data-aspectratio="{{ block.settings.image_2.aspect_ratio }}" data-sizes="auto" alt="{{ block.settings.image_2.alt | escape }}">

Handling Placeholder SVG Tag Display

At times, you might encounter issues with displaying placeholder SVG tags. These tags are crucial as they provide a fallback option when an image fails to load.

Consider the following piece of code:

```html {% else %}

{{ 'image' | placeholder_svg_tag: 'placeholder-svg' }}

{% endif %} ```

If your SVG placeholder isn't displaying correctly, ensure that you have the correct path and file name for your SVG file. For example, if your SVG file is named "placeholder" and is located in the "assets" folder, your updated code would look something like this:

```html {% else %}

{{ 'assets/placeholder.svg' | placeholder_svg_tag: 'placeholder-svg' }}

{% endif %} ```

Optimizing your Shopify image tags is not a one-time task but a continuous process. With the right knowledge and a bit of practice, you'll master the art of Shopify image tagging in no time. As we always say at First Pier, the devil is in the details, and mastering these details is your ticket to a more efficient, user-friendly, and profitable online store.
