After deleting photos, memory in my iPad is still used. WHY?
When connecting my iPad mini to iTunes on my MacBook Air it shows that I have 2489 pictures on the iPad and am using 28.4 GB for all those pictures. When I open the Photos app on my iPad it shows that I do not have ANY pictures on the iPad, which would be correct, as I have deleted them all. So why are they still using up all that memory? How can I clear the memory to make it available again? BTW, My iPad Settings>General>About agrees with iTunes. It shows that I have 2452 pix (why not 2489 as above?), and am using 28.4 GB for them. So again, HOW CAN I CLEAR THE UNUSED MEMORY, or get rid of the pix if they are indeed still hiding somewhere on my iPad?
My iPad mini is running iOS 8.1.1
Thanks for any help....
