this sould be the best extension, BUT. if picture/image is in some kind of frame (faceboo, for instance), image doesn't show above frame, it goes under frame. so it is visible only enlarged portion of image. i don't know is that feature or bug, but i'd like to have something like "image zoom+" or "imagus" - when i stop cursor on image, then image shows in it's whole size. AND, in every case, i'd like to see option to save that enlarged image, or at least original size (which is often smaller in page). i'll wait with uninstall, and test in other pages. but, frames "frame" me in using it.
