[WM] Webmake not finding certain images.

[jlm17]

I am getting some errors with webmake like this:

Use of uninitialized value in string eq at /usr/lib/perl5/site_perl/5.8.0/HTML/WebMake/Main.pm line 
1732.
Use of uninitialized value in string eq at /usr/lib/perl5/site_perl/5.8.0/HTML/WebMake/Main.pm line 
1732.
${IMGSIZE}: cannot find image file "images/cygwina.jpg" in "(html-cleaner)"

My output files go into .. (the source directory is a subdirectory of the publish dir). ../images 
holds a number of images used throughout the web site. For some reason only about 3 images are 
unable to be found. These files are indeed in ../images and their permissions are the same as the 
others.

Further investigation shows that this happens when the -F flag is used. Also, it only occurs with 
files that are gifs and jpegs. pngs seem to work correctly. I converted one image from png to gif, 
renamed the file in the wmk content and webmake says it is not found.

Has anyone else seen this? Since I successfully debugged my previous problem I am reasonably 
confident in figuring this one out but I just wanted to run it by the list first.

Thanks.
