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.
