Right now I have a website based on VBulletin 4 CMS. It has an addon called Photopost VBgallery.
We are about to migrate from Vbulleti to PHPFox 3 and need the photos and user stats to be migrated from Photopost VBgallery to PHPFox.
I have a test site so that you may see what needs doing. Photopost Vbgallery keeps the photo's in directories and is a php script.
TBH we don't have a huge budget as we are a non profit org, but we are open to offers so please feel free to contact us.
