Help Picture playback on Camera... help!

[nenahog]

I cant figure out how to look at all my pictures on my camera. I like how it looks when I want to send a picture via text (everything shows up in folders for me to choose from)but if I just go to camera roll on my Camera app to look at pictures, I only get pictures I have taken with the camera, not downloads, sd card, etc. Can I somehow set the camera roll to let me see everything like I see it when I go through the text msg app?
