Wallpaper Slideshow Pro turns your photo collection into a beautiful, ever-changing desktop experience. Set your favorite images as wallpaper and let the app cycle through them automatically -- every few minutes, every hour, or on a custom schedule.

Designed for power users and photo enthusiasts, it offers full multi-monitor support with independent wallpapers on each display, smart image resizing that fills the screen without distortion, and creative collage modes that arrange multiple photos as scrapbooks or mosaic walls.

Customize every detail: overlay file names, EXIF data, or a calendar on your wallpaper. Filter images by rating, keywords, or orientation. Organize collections into groups and switch between them with a click or hotkey. Set up weighted randomization so your best photos appear more often.

WallpaperSS Pro supports JPEG, PNG, TIFF, BMP, GIF (including animated), and more via WIC codecs and plugins. Runs quietly in the system tray with minimal resource usage, and includes features like auto-pause on battery, color management (ICC profiles), and smooth wallpaper transitions.
