I think you may be looking for the image map feature of HTML. You can use it either to define various areas of an image to be treated as links, or request that the browser report the location of the click on the image as query-parameters when following it.

I think you may be looking for the image map feature of HTML. You can use it either to define various areas of an image to be treated as links, or request that the browser report the location of the click on the image as query-parameters when following it. This won't work if you're unable to supply the necessary HTML, though.

Formats other than simple images - objects such as SWF, SVG, IFRAMEd pagelets, Java applets and so forth - would be needed to carry the additional information necessary to embed a link.
