I added pictures to my phone from itunes but i want to delete some of them but i can't figure out how to on my phone or itunes? Can anyone walk me through it?

Www.youtube.com will show you how

1.) Go to the Photos app
2.) Go to your Camera Roll
3.) Tap the edit button (it's in the top right corner)
4.) Select (Tap) the photo(s) you want to delete and in the bottom right corner a red button saying "DELETE" should light up
5.) Tap the delete button and the photos will delete permanently.
Make sure you delete them from your photo stream album if you have photo stream turned on.
