I would like to echo Steve's condolences and wishes for you.
I looked at the Gallery on my PE. It has images from all my files as well as every shot taken by the camera, organized by folder. I also found an empty folder in my file structure called Pictures, which would be a logical place to put your pictures.
Do you know how to make a new folder using ES File Explorer? (Menu button, tap New, tap Folder from within the folder where you want the new one to appear, e.g. /sdcard/Pictures/.)
I'm sure your daughter will love this gift!
