Falbum upgrade changes URL, old one doesn’t work

I just upgraded my Falbum plugin and the file/directory structure is different. This means that all my old links to photos do not work!

Does anyone know how I can rememdy this situation?

I was forced to upgrade by my host because the old script was attacked by a hacker and overloaded their servers.

Thanks in advance for any help and let me know if you need more information.
