@PowerJack Sorry for the late reply, I was busy on another project. I believe there is an interface that can actually set wallpaper individually. It is called IActiveDesktop with the method SetWallpaper. I will try to find some times to look it up more closely but it seems promising.
@mLipok This one below fixed the problem. I was adding them one at a time and removing the others. I will keep this list for future use as I write a lot of other scripts. Thanks VERY much for the quick response. @Danp2, thanks for your help as well. You guys are awesome.

I went the extra mile last year; it was a challenge in the beginning, but - for me - absolutely worth it.
Once a script is saved, AU3Check is run automatically and shown in the problems tab.
