Thanks for submitting that potential issue. Unfortunately, that wasn't the case at all. Fortunately, it led me to discover the actual issue with the way the server was handling the mod.rewrite script. I ran the &debug command with the image URL and found that ZenPhoto did not believe the image existed. the mod.rewrite command was skipping the /album/ section of the URL (which, had mod.rewrite worked properly on my server wouldn't have been a problem), and was thus causing the image handler to look in the wrong directory for the photos.
I had to disable mod.rewrite in both the .htaccess file, along with in the ZenPhoto admin options. Only be deactivating it in both these locations did the server fetch the proper image URLs.
Thank a bunch for your help and have a nice day!
