I was able to do a full stripping of the WebAssist code to brand it as a custom gallery by adjusting the templates. I don't have time right now to document everything I did but just wanted to do a quick reply to assure folks that it can be done pretty easily!
I further pimped the gallery for a client to allow for multiple galleries to appear on one page and the visitor can select which gallery to view.
gallery.php
It was a bit of work but the client loves it - and the admin is custom branded with no link back to WebAssist.
