Ok I have a curve I go into media and look at my pictures then I pulled my sd card out to see what pictures I had saved on my phone, when I put the card back in, it pulled up all pictures I have ever taken, I could see the tumbnail but not pull up any of the pictures. Now there are some pictures I have deleted that I would like back and some I would never want to see again. What can I do to delete forever and what can I do to pull back pictures I have deleted.
