To use responsive images, you can use the “srcset” attribute in the HTML “img” tag. The “srcset” attribute allows you to specify multiple versions of an image at different sizes, and the browser will choose the most appropriate version based on the device’s screen size and resolution.

For example:

Image Code

In this example, the browser will choose the “small.jpg” image for devices with a screen width of 320 pixels or less, the “medium.jpg” image for devices with a screen width between 321 and 640 pixels, and the “large.jpg” image for devices with a screen width of 1280 pixels or more.

Using responsive images can help improve the loading times and user experience of a webpage on mobile devices. It is an important aspect of mobile optimization and should be considered as part of any image SEO strategy.
