Annotating images with CSS

I'm not unique in my dislike of the use of Flash to provide annotations on Flickr. After experiencing similar frustrations, the author of Annotating Images with CSS, came up with a number of techniques that allow image hotspots to be annotated, using just CSS (no Javascript is needed).

The technique works great on CSS2 compliant browsers - which means that Mozilla and Firefox are fine, but IE is not supported, due to its deficient handling of :hover. The examples also make use of transparent pngs, another area in which IE is deficient.

The article provides links to a few other techniques, some of which use Javascript to provide the annotations.
