Do I have to approve every imagemap my users create?Not if you update to the latest and greatest imagemap software. The problem is that the NCSA web server imagemap program used to require a central configuration file. This restriction has been lifted in version 1.4 of the NCSA web server (read more at <URL:http://hoohoo.ncsa.uiuc.edu/docs/tutorials/imagemapping.html> ).
The CERN imagemap program never did have this restriction (consider <URL:http://www.w3.org/hypertext/WWW/Daemon/User/CGI/HTImageDoc.html> ).
Also consider Jutta Degener's "umap" ( <URL:http://www.cs.tu-berlin.de/~jutta/ht/umap.html> ), a flexible alternative to the standard imagemap utilities.
