With my new laptop I got a screen with a 1920x1200 resolution, so I went out looking for wallpapers for the resolution, because my existing ones degraded in quality with that size.
My search led to Deaddreamer from which I have my current wallpaper as well.
But nowadays he got so many good ones, so I picked up 5 1600x1200 wallpapers. And now I want a random wallpaper each time I logon.
Having some spare time (very rare) I created something small myself, I'm sure there are tools out there to do all that.
Originally I wanted to use PHP to get a random number and set the wallpaper, and then call the php script with a bat file and set it as a scheduled task. But that kept popping up a dos prompt each time it set it, and my wallpaper disappeared after boot (some bad registry settings).
So I used KiXtart to set the wallpaper and then link it with a shortcut which would run minimized.
That worked for one paper, but when I tried the RAND function in KiXtart, it didn't go well.. But I had the php script and bat still there so I let that make a random number and then kill the KiX script with that number as argument.
Result: Shortcut to wall.bat, which calls wall.php, which makes a random number and calls wallpaper.kix with the number, after which my wallpaper is set, and saved in registry.
I have to shortcut Run as minimized and on logon and every hour, and now I got a nice random wallpaper implementation.
Overly complicated? Maybe, If you have php installed, it's a small solution, otherwise you need a 1.3Mb dll and 24k php.exe in the same dir, which isn't really something bad.
I have zipped everything and written the steps to install it out in a Readme.txt for everyone wanting it as well. I also included the php.exe and dll.
Download it here: RandomWall.zip (706Kb).
And now I have sweeeet super-detailed wallpapers auto-changing without any special timer programs running, but just the Scheduled Tasks :)
Here are my wallpapers:
(convert them to .bmp first, not sure if it's required, but whatever, bmp is nicer, no need for desktop to go in Web mode)
