Database corrupted. How do I transfer pictures to new install?

I had an updated version of Gallery2 installed on my server and about a month ago something happened that corrupted a pile of tables in the database. I created a new install and I was wondering if there was a way to migrate the images out of the old install and into the new. Or is there a way to point the new install at the same folder on the server and somehow migrate the metadata in the database? What's the best way to fix this?
