Script Summary: Expands tiny/small images to their next big size on mouse hover.
This script is no longer supported. Instead, check out FLUTE: FLickr Ultimate Thumbnail Expander, which is a much more radical and exhaustive image expander for Flickr.
This one was my private Greasemonkey script for enlarging the tiny pictures in Flickr's stat pages. It doesn't do much besides this for now. Let me know in Discussions if you have a feature suggestion.
