Try this:
1. Start from the homescreen of your Iphone/pod (for dummies: where all of your "apps" are).
2. Look for an app on your homescreen titled "Photos", when you find it - Click it.
3. When the app opens, go ahead and look towards the bottom of your phonescreen.
You should see a navigation with three different options;
"Photos", "Shared" & "Albums"; Why don't you just go ahead and click on "Albums", there we go - Very nice!
4. On the next screen that appears, it should display your different albums.
Look for "Recently Deleted", and when you find it - Click on it.
It should be on that list somewhere (or there's a problem!).
5. Now you should see a screen displaying all of the recent photos you've deleted.
The term we know as "recent" to iOS is thirty days (that's 720 hours in people-time!).
You will have to click to each individual photo, however at the bottom left-hand cornor of every photo take notice of the 'Delete' option.
You're welcome. 😉
