Whenever I move a picture to a folder it moves, but when I go back to the main media page and back into the pictures, the pictures are all back where they were prior to being moved. Anyone else experiencing this problem? Any fixes?

Also, how do you move multiple pictures into a folder at once? It was possible on my Pearl, but have yet to find out how it's done on my Storm.

The multiple move can't be done ON the device, but rather from the PC with Mass Storage enabled.

For you, for now, I'd try a battery pull reboot and start again. Often the memory cache needs refreshing since it apparently stores the Media Card "location cache" in the device memory.
