Where do I find help for the gallery on my Android dragon tablet?

[AC Question]

I want to add photos from external storage to the Gallery on my tablet

Gallery shows all pictures in both internal and external storage that Media Scanner finds. Media Scanner runs when you do something media-related (like taking a picture) but not when you do something like copy files or plug in a card or USB stick with pictures on it - you can run media.Re.Scan to force a rescan.

(You don't "add pictures to Gallery" - Gallery has no particular place to put pictures.)
