I tried to erase it in iTunes and it won't appear in my iPhone memory in iTunes. .So I erased all folders/pictures in my iPhone by syncing and they all got erased except the Camera Roll folder which is fine. . When I tried re-syncing my iPhone with only the Photo folders I selected in my computer, the same Photo LIbrary will again be in the iPhone with all the pictures intact. I tried doing both when I am on-line and off-line. Same thing. The Photo Library keeps coming back. I really would like to erase only certain photos. Anyone has any idea how to go about this? Thanks!
