Picture Viewer shows hundreds of images I didn't set up

[IT_Architect]

The picture Viewer shows hundreds of images and albums I didn't set up. I see images from games, my Android install on my microSD, emotions, a bunch of dice images, probably from a game, etc. I end up with large cache and thumbnail files, what a mess!

It wasn't always like this. I just want the pictures from the built-in camera and video camera to show. What happened? How did I get rid of all the junk without deleting the underlying images that programs depend on?
