On my main PC and at work I use the excellent John’s Background Switcher to randomise my wallpaper and, in the case, of work display different ones across my multi-monitor setup. It works well and, due to the amount of time I’m usually on them, changes regularly throughout the day.
For my Netbook, however, it’s different. Due to its short bursts of use, changing regularly isn’t so important and, at the same time, I need a program that’s compact and uses as few resources as possible.
Step forward Craig’s Random Wallpaper Changer. This has no options, no GUI interface. Nothing. You simply drop it into the folder that your wallpapers are stored in and then create a shortcut to it in your Startup folder. It will then randomise your desktop background on startup. And that’s it. It then finishes and uses no more resources.
It’s a superb idea and I highly recommend it.
