update... I copied all the images that were created in my secure_html/bmz_cache folder to my public_html/bmz_cache folder, which seems to work with some quirks in the meantime (it's a live site... I know, I know).

I also added to call out for the jscript and css file to my html header, so the zoom works now.

But I still need a better fix for my split folder system. Any thoughts?
