photographic favicons

Tee hee, each photo entry on this site now gets as a unique favicon a 16x16 version of the photo itself. Looks kinda neat when you open a bunch of them in tabs (try it out by middle-clicking some of the id numbers of the entries below). I love it when ideas go from thought to successful implementation in less than 10 minutes. Update: adding a photo to this entry so you can see it in action right here...
Oh, and this only works in a browser that supports .jpg favicons, so you Internet Explorer users won't notice anything (not that favicons ever work correctly in IE anyway).
