phpThumb: changing directory path when moving a database

Hello,

I recently moved our WordPress blog from one server to another. Had a very successful transfer of all of our posts, articles, comments, and forum topics.

The only thing that I noticed that got broken in the move was the directory path to thumbnails generated by phpThumb. I cannot locate where I can change this information.

Does anybody know what php script needs to be modified in order for my blog thumbs to show up?

Thank you in advance for your knowledge!
