Thanks very much David and Kynn. I summarize your arguments for server side maps: it is historical - it used to be done that way. Bottom line - no reason. I don't buy computation or "funny shapes" because any funny shape can be fit to pixel width by a polygon. But, David, guess I ought to ask what is the "linkshare program."

Serverside imageamaps are used for one of two reasons: 1. Historical - serverside images were common before browsers supporeted imagemaps. This has not been the case for quite a while. 2. Dynamic content - when the resulting link is based on "computations", it needs to be server based. The common example of this is linkshare programs Hope this helps. dc --------------- David M.

I am assuming the developer knows accessibility and the requirement for equivalent text links. What are the advantages of server side image maps? I had always thought that it had something to do with unusual regions. But the client side map at http://support.dell.com (WITHOUT alt text on the areas) illustrates the fact that you can get as exact as you want with the regions.
