If you have an iPhone and you want to delete photos that are still in the camera roll, there are a few steps you can take. First, open the Photos app and select the photos you want to delete. Then, tap on the three lines in the top left corner of the screen and select “Delete.” If all of your photos are in albums or folders, then those will also be deleted when you delete the photos from your camera roll. If all of your photos are individual images, then just select “Delete” and it will delete them all.
