Hi
Welcome to the HP Support Forums. I understand that you are experiencing paper jams when trying to print photos. I would like to help.
If it is a settings issue, this link will help you to adjust the settings to print a photo. HP Officejet 4630 Printers - Printing Photos (OS X).
If you are still having an issue, it is either an issue with the photo paper or the printer. These links should help with those situations.
HP Printers - How to Store and Handle Paper to Avoid Paper Jams
