go into your itunes and click on the little phone icon. Click on ""photos"", then make sure there is a little check mark in the ""Sync Photos from"" icon, choose the Desktop , and click apply in the bottom right of the screen . You should get a ""remove ...message"" and hit ok.

You can just go ahead and restore the iPhone and that should solve the problem in about 20-60 mins, depending if you need to download the required IPSW.

To wipe iPhone all photos permanently ,you need to use a professional iPhone eraser application. To save your time ,you can try Coolmuster iOS Eraser which is a quicker and easier data erasing process on ios devices at once.
