- Set the image’s loading attribute to “lazy,” by default
- Add width and height attributes to the image
- Use the resize_image_url function to resize the image
- Use srcset and sizes attributes
Explanation: When optimizing images within a custom module, there are several techniques you can employ to improve performance and accessibility. Setting the image’s loading attribute to ’lazy,’ by default is a recommended practice to defer the loading of images until they are within the user’s viewport, reducing initial page load times and conserving bandwidth, especially for images below the fold. Adding width and height attributes to the image specifies the dimensions of the image in the HTML markup, allowing the browser to allocate space for the image while it’s loading, preventing layout shifts and improving rendering performance. Using the resize_image_url function to resize the image dynamically generates resized versions of the image, reducing file size and optimizing images for various viewport sizes and device resolutions, enhancing page load speed and user experience. Using srcset and sizes attributes enables you to provide multiple image sources and specify different image sizes based on the user’s device capabilities and viewport size, ensuring that the browser can select the most appropriate image for display, further optimizing performance and responsiveness. By implementing these optimization techniques, you can significantly improve the loading speed, user experience, and accessibility of images within custom modules on your website.
