Deleting photos from your iPhone or iPad with OS X

If you have more than a handful of photos you want to delete on an iPhone or iPad it can be a bit of a pain to do manually and I often find on my 4S that if you have too many photos, deleting the entire Camera Roll through Settings -> General -> Usage just doesn't work. Here's how to do it with a Mac.

NB: This will permanently delete photos from your phone, make sure you've backed up or sync'd anything you want to keep before doing this.

1. Connect your phone via USB to your Mac.
2. Open the Preview application, the easiest way is to search for it using Spotlight (the magnifying glass top right).
   
3. Once open, from the File menu you should see your iOS device listed, mine's called "Richard's iPhone". Select Import from....
   
4. You'll then see thumbnails of all of the photos on your device. I clearly like coffee =).
   
5. Now select the photos you want to delete, either individually (holding down CMD to multi-select) or CMD-A to select all.
   
6. And hit the delete button at the bottom.
7. That's it.... it's as simple as that, you're photos will be deleted.
