I don't know if it's still the case, but links with a 0 font size used to penalize you with search engines. Probably not a concern but just fyi.

Subject: Re: [CODE4LIB] image maps + lightbox/thickbox/ibox/etc -- SOLVED


Sometimes the answer is "quit working, go home, and ask your sweetie".

My partner is a genius and had a very straightforward solution: get rid of the imagemap and replace it with some absolutely-positioned links that use regular anchor tags. Not only does this solve the problem in a lightbox-friendly way, it also improves accessibility -- the links are now text with a font-size of zero: usable for a screen-reader and invisible to others.

Simple demo here: http://www6.wittenberg.edu/lib/testbed/imagemap/

Tomorrow perhaps I'll write a little script to convert my image maps to absolutely positioned elements for the more complex real-life image maps.
