So I wanted to change the wallpaper on my logon screen for Windows 7. I found some great articles online on how to do it. Then I decided to create a quick little app to make easier for me and anyone else to change it in the future.
It works around the limitations of Windows. For example Windows 7 only supports JPEGs, this tool supports many other formats including PNG, BMP, and TIFF.
It also gets around the Windows file size limit of 256 KB. It gets around this by compressing image and adjusting the size to fit the screen.
The interface is very simple, just a button to select the image you want to make into your wallpaper background, and another button to remove it.
