For that reason, I also have another feature that will be coming in a few months. You will be able to use custom DNS so you can keep full control of the traffic.

So, if you decide ThumBuilder isn't for you, but you have ~500 galleries published, you can just reroute your domain name to a different server to monetize the traffic.

Exporting galleries is a possibility but I haven't found a way to address that yet.

As far as hotfixes: until I have the custom DNS feature launched, you can always setup each gallery to be forwarded from a server with a PHP redirect script or .htaccess - whatever suits your needs.
