When an editor submits a cover image URL, method cgi2obj in common/pubClass.py checks that the submitted URL is for the image and not the the Wiki page the image is on. The current checks says:
if value[0:41] == '%s://%s/index.php/Image' % (PROTOCOL, WIKILOC) -> error
It works correctly with the current ISFDB host name, but it may fail if the database is moved to another host. The check should be made more robust.
