Photo Stacker is a versatile application designed to help you create stunning wallpapers using your photo collections from your hard drive or web services like Picasa and Flickr. With Photo Stacker, you have the flexibility to generate wallpapers in two unique styles: a dynamic, disordered layout that mimics a pile of polaroid photos scattered on your desktop, or a neatly organized grid where you can customize the number of rows and columns. Additionally, you can personalize your wallpaper by selecting a background color or image, designating areas where no photos will appear, and even setting a timer to automatically generate new wallpapers at regular intervals. Transform your desktop with Photo Stacker's creative and customizable features!

I’ve been using Photo Stacker for a few weeks now, and it’s been pretty good! The effects are nice, and my photos look crisp. I do wish it had more customization options, though. Still, I’m overall happy with my experience!
