Very good, very fast 1000x better than the built-in photo viewer from the Kindle. Have 394 photos brought from Ireland, the Kindle displays them, but as you move it takes EVERYTIME endlessly until it shows thumbnails - presumably because he re-read every time and the display builds up again until. Although Quick Pic used during initial display even until it displays all photos, then it's done but Rip-Rip! To take pictures or watch then look really fun. Use the built-in photo viewer no longer, only more Quick Pic, especially since the program offers also the possibility a slideshow - all for free! 100% their recommendation!
