An ever increasing number of photos get stuck on computers without ever being seen, in the era of digital cameras and smart phones. Dust off your photos, and put them in your Android devices, and view them with music and 162 transition effects, just like a slideshow.

You can specify the interval between photos in transition, and decide the quality of transition effects.

Happy Photo Viewer also allows you to crop out your photos or snip any portion of your interest out of your photo, as well as to edit your photos with such special filter effects as warm, mars, reminiscence, gradual, pulsar, blur, wave, paper sketch, contrast, pixelate, sharpen, and mosaic.
