How to delete photos on iPhone that are permanent?

I put photos from my computer to my iPhone trough iTunes. Then I wanted to delete some of the photos and I couldn't. I clicked the edit button to delete the pics and all it said was share and add to. Help Please!

The only reason that you can;t delete them from your phone is because you can only remove photos from your Camera Roll. To remove photos from other folders, you will have to deselect them from iTunes or remove them from your My Pictures folder on your computer.
