I think those are the only Marders I have right now. It's not for me to say whether you may or may not use the image. They aren't my personal artwork. The images shown are just my suggestions for possible desktop backgrounds. I only post reduced sized images of the originals. If you use Google image search you may be able to find the full sized version yourself. Using the image I posted won't look very good on the desktop because it will be all blurry when it is enlarged.
The artist's page for that work is
http://www.3dartistonline.com/image/294 ... ds_kharkov. I actually found a larger version on a "wallpaper" website that specializes in military art. I don't make notes on where an image comes from so I can't tell you which one I got it from.
