Well since myself and others have already sent the email as the first few people, I think I will provide a little more help. You are not looking in the source code, you are looking in an image. The image is from the most recent set of clues tonight, and there is only 2 images. Do not look too hard, look up into the images and see what you find. Only one image has the wanted source. Look up into it, you'll find it. It's really obvious once you find it. Happy hunting!
