Okay you can do that but you need to state what your not understanding with what we are telling you. You made a backup of a database and you have even imported that backup into the new database so you have done both processes here. So you know what you have to do. Let me recap what I have stated above even simpler here. You deleted all your photos because you did not correct your paths when you moved servers so you need to get those photos back. I outlined specific actions my previous post but lets see if we can get you straight here.
1. open your backup of the database
2. delete anything in there that does not start with
INSERT INTO pp_photos
3. save the backup
4. import it into your new database
THATS IT your done. After that you should have your photos back because all your worried about reimporting is the pp_photos table inserts unlike what you did before was importing a full backup.
