Thank you for this very cool app. I had an Idee to change also the Windows 7 Logon Screen Wallpaper. There is a way to accomplish this as described here:
There are only a view steps to get it working:
Enable OEMBackground Registry key;
Change PictureThrill Folder for downloaded Pictures to "C:\Windows\System32\oobe\info\Backgrounds";
check if Picture is < 256 KB and
create a copy named backgroundDefault.jpg
Would it be possible to add this functionality ?
