How do I delete all the photos from only my I phone 4S

You can delete camera roll photos by opeing Image Capture, connecting your phone to your Mac, then selecting the photos you want to delete and click the red circular icon with the diagonal line through it on the bottom.

To delete photo library photos you have to sync them off by deselecting them on the Photos tab of your iTuens sync settings and syncing.

If you delete photos from your my photo stream album, they will be deleted from your photo stream and other devices connected to your photo stream.

Oh so totally cool! I've been carrying those photos around on my phone for so long. I didn't need them because I already had them in Aperture 3. Thanks!

YES you can delete all photos with one easy swipe~!!!! I just discovered how by accident when I went to delete my audiobooks for more storage!! You go to SETTINGS > GENERAL > USAGE > PHOTOS & CAMERA > and then just decide what you’d like to remove~~ either (or all) “Camera Roll” “Photo Library” or “Photo Stream” & Swipe to Delete! Happy deleting everyone!!
