Image problems after moving a multisite installation from one server to another

Hello,

I hope somebody can help me with a problem I’m facing with a website that is part of a multiuser network.

I zipped the whole directory, exported the database from the first server, then created a new domain on the new server, unzipped all the files, imported the mysql data into a new database, created a *.domain.com on the new server and everything works ok … except for a few bugs.

I can’t see most of the images in the Media Library or the thumbnail on the home page. They’re all broken.
