the storm trooper image is actually located somewhere on my tumblr page. this screenshot was taken ages ago. therefore, this particular image will most likely cause for extremely tedious searching in order to find it. my tumblr page contains thousands of images, which i update weekly. so, if you want to try and find it be my guest but sorry i couldn't help you out any further.
and no worries on the english language. it's a bitch.
oh, and my tumblr link is in my signature (below).
the photographer requested i take it down, so i did on his behalf. nevertheless, if you scroll down a couple of comments, you will come across an external link download that i posted for those of you that still wanted the wallpaper. pip pip, cheerio.
