Yeah, I had already upped it for another site with my name on it, so I threw it in. It was a convenience thing, is all - But I agree, it's a bit redundant.  

You don't need to pre-zoom your art for PJ. If your whole piece fits as the preview image, you don't need a detail file anyway. I realize the big version is different in that it has your name in it, but it's really just redundant since the textless preview is right there anyway xP
