Command Line Wallpaper Changer Portable is a small and fast tool to set your windows desktop wallpaper. Simply drag 'n' drop a JPG or BMP image file on CLWCP and it will be set as your new wallpaper. You can also use the command line to set a new wallpaper. This way, you can even define, whether you want it to be tiled, stretched or centered: Start clwcp.exe with the filename of your desired wallpaper as first parameter, e.g. "1.bmp" or "1.jpg", followed by the optional parameter defining the alignment: "stretch", "tile" or "center". A JPG will be converted to BMP and saved as clwcp.bmp in your Windows folder, then this file is set as new wallpaper. This version is the first release on CNET Download.com.
