#155: Responsive Images, WordPress, and Cloudinary

Eric Portis joins me to dig into the world of responsive images.

We start at the basics. Responsive images are specifically images in HTML and exist because of a desire for better performance. Images are probably the biggest culprit in the overall weight of websites. If we can avoid sending too many pixels across the network, we should. After all, a screen that is only 720 pixels wide doesn't need a 2000 pixel wide image, even if it's a 2x display.


Responsive Images in WordPress with Cloudinary, Part 2

In Part 1 of this series, I provided some background on responsive images, describing how you can add srcset and sizes attributes to an img element to serve appropriately sized image files to users of a website based on the size and capabilities of their browser and device. I also shared how WordPress used its native image resizing functionality to implement srcset and sizes automatically and how you can use an external image service like Cloudinary to extend the native implementation that WordPress provides.
