Makes all images in posts, both embedded and attached, resizeable by dragging on their bottom-right corner, just like a textarea. Useful as a substitute for lightboxes if your users like to create links on their images, which would contraindicate a lightbox because then clicking the image would both enlarge it and send the user to a different page. Plus, this way, users can easily zoom in and out of images as much as they want.
