when i import from my sd card, it always comes up with this question asking me whether or not i want to delete the photos on the sd card that i just imported. when i say keep photos i have not a problem, but when i choose delete photos, it does indeed stop me from seeing the pictures but it still takes up the same amount of space as before. so if i had space to take 1000 and took one hundred, then imported and delete, i will still only have 900 photos available to take but cant see the photos that are taking up that space. Little help?
