This question already has an answer here:
I have synced a folder which contains some pictures to my iPhone. The synced photos are successfully copied to my iPhone. But I can not see any "delete" option in my iPhone to remove the synced photos.
The "Camera Roll" which has the pictures that I took via the iPhone's camera have an option "delete" in the bottom of the picture. But synced photos does not have that delete button.
Should I use iTunes/Mac to delete synced photos? Can't I delete the synced photos with a single touch?
