Every other forum I've been in has pictures aloud sigs, and it doesn't make anything worse, in fact, it adds more appeal to the forums. Makes it look prettier. Anyways, maybe you could *try* the pictures in sigs, and if it doesn't go well, remove them. Just talking about what you think will happen won't solve anything. Actions speak louder than words.
And also Eiii, if you had any photoshop talent whatsoever, you would know that that image is not just copy + paste and filters. Maybe when you can make something nearly as good, you can talk. Until then, keep those comments to yourself.
