Ah! That does indeed fix the problem. Thank you very much!

Unfortunately there is yet another problem. Some background. On my site, 
only pages in CommentPages and three other groups can be edited by 
users. Pages from these groups are included on pages in the private 
group EpisodePages. I find now that my test image reappears when the 
CommentPages page is included on the EpisodePages page. Is there some 
way to prevent the "include" from restoring the image? I did notice that 
this image is not a link to itself. Links to images from the user 
editable pages should be allowed. And, images, added by myself, are used 
in EpisodePages. Thanks, again, for your help.

I may be worrying about this too much. I have had no problems with users 
posting "bad" images. And, no matter what can be done, I will still have 
to check every user addition. :-)
