This is not an original image. It is a derivative of this. http://www.gnome-look.org/content/show.php/Dragon+Flame+-+blue?content=80514 These images are partial transparency versions of the original. Four versions. The screenshots show examples of what you can do with a gradient as a color behind the image it's self. Like the original these images are 1280x800. The source archive contains the .xcf file with all the layers. One of those layers is the original image.
