The image below is mapped using the ISMAP option of mosaic. The anchor that this image belongs will translate to a script execution that links portions of the image to other anchors in the text. The /$mapimage/ HREF reference in the image anchor invokes a special builtin imagemap handling by the server, change it "/htbin/mapimage/demo/nagel23a.imagemap" to the DECnet-based (WWWEXEC) script instead. The presentation method demo uses the WWWEXEC script.

Script Method:
