Super Photo Slider is built using AndEngine. It is a cool open-source game engine for Android. It is easy to use and learn and there are some online resources to help out as well. The only downside is that the documentation is quite bare.
The photos used in the game are mainly family vacations, trips and events, and some random other pics from friends.
Thanks to SoundJay for use of the music tracks and some sound effects.
Also thanks to Noiseforfun.com for use of a couple sound effects.
