Pic Collage is a free service for quickly creating picture collages on your iPad or Android tablet. The app does not require you to register or connect a social network profile in order to create a collage. If you do connect a social network profile to Pic Collage you can pull in pictures from those accounts. Otherwise you can upload pictures that are stored on your device or take new pictures using the Pic Collage app.
The Pic Collage user interface is easy to use. Just tap the blank canvas to import pictures from your device, from a social network profile, or by taking a new picture. To arrange the images in your collage just touch and drag them. You can expand or contract the images by pinching on them.

Back in June Angela Oliverson wrote a great post about using collages pique students' interest in books. I encourage you to read that post.
