Nope, I'm afraid you're stuffed as no matter how big any other version of this pic is, it'll still be the same barely (no pun intended!) useable pic.

I will check to see if they are on here, if not I will try and find them somewhere else.
I personally don't care if a member has no posts before making a request, so long as it's polite.
