A slower website causes decrease in sales due to increase in bounce rate.A responsive image offers different sizes of the same image. The browser decides the best image size to render. Divi includes a fullsize and regular image module. They don't serve a responsive image. It's a one-size-fits-all. The non-responsive image have a single image size. The same image loads on large desktop, tablet and mobiles.
Let's say you use the native divi image module with image of size 2000px. Serving the 2000px wide image on a device with width 400px serves no purpose other than to slow down the webpage.The Solution – Divi responsive image size plugin The Divi Responsive Image Size plugin has two modules.
Both the modules help creates a image tag with responsive image sizes.A responsive image adds the srcset and sizes attributes to the image markup. What does srcset and sizes do? Consider the example of an <img> tag
<img alt="Divi responsive image sizes" src="default.jpg" srcset="small.jpg 240w, medium.jpg 300w, large.jpg 720w" sizes="(max-width: 360px) 300px, 100vw">Let's go over each attribute.
alt="Divi responsive image sizes"`The
alt
attribute describes the alternative text for the image. Browser loads this text when it can't find the image.
src="default.jpg"The
src
attribute defines a fallback image path for browsers that don't support srcset and sizesattributes
srcset="small.jpg 240w, medium.jpg 300w, large.jpg 720w"The
srcset
attribute lists images at different sizes. Along with each image path we specify it's width in pixels.
sizes="(max-width: 360px) 300px, 100vw"The sizes attribute instructs the browser on how to pick the right image from the srcset based on the viewport (device) size. Going by the above example,
Divi Theme from Elegant Themes is a pre-requisite to this plugin.
