I already published a question about a problem with a wordpress theme on the following link:
BUT I think that there is a relation also with the PHP code, because the same site was moved from an old server to a new one, and the only thing that was changed, it's just the photos on the homepage, that doesn't appear anymore. I already tried to resolve the problem with installation of PHP GD on the server, but without success, can you give me your opinion ?
Check your other thread. And try not to cross post!
