From the developer:
Photo Show Pro is a slide show producer with extensive photo sharing features. Any number of slide shows can be created with music and transitional effects using 3D objects. The photos can be obtained from your computer, your LAN, WiFi devices, social networks, and eMail accounts. Also, you can add effects to each photo during slide show creation, or at a later time.
