Are they stored as jpg or gif files or a different format. I have backups of that directory, but I don't see image files.
They keep its original format bu they don't have file extension.
When files are uploaded they are stored with a random name to avoid file name collisions.
Just restore them and they should work, provided that your FTP client was configured to transfer files in binary mode or during the copy via SSH (scp or rsync) they were not corrupted.
