Wallpaper Montage

From Flat Iron Software:

Wallpaper Montage is a desktop utility that will create desktop wallpaper from existing images on your hard drive/network. Wallpaper Montage will load random images from "watched folders" you set and automatically convert these to a desktop wallpaper. You can set Wallpaper Montage to change the desktop wallpaper at any interval, i.e. every 10 minutes, every hour, or every day. Wallpaper Montage offers the following features: joining of multiple images to form one desktop wallpaper, scanning of multiple image folders for graphic files, custom size montage based on number of columns and rows, i.e. 5 cols and 4 rows would equal a desktop wallpaper with 20 images, custom wallpaper rotation, and you can specify a time interval to have the wallpaper redrawn with a new random image wallpaper.
