Hi Gregb do you know whose pictures you are asking about?

Welcome to GoY too.

Greg there is no central office that deals with members questions - it is up to individual members to respond. You will need to ask the member who posted the photo. You can do this by finding the original post (I do remember seeing this but can't remember who posted it or when, sorry!) You would have to scan through all the old posts until you come to it.
Then you can then either add your question to the bottom of the replies or send him a Private Message asking him politely if he would be kind enough to show a close up. If you need help let me know.
