Thanks Guvner. I have no idea if that's the same stuff Gary was talking about; The Camping World photo doesn't show a cross-section to be able to compare it.
BTW there's no need to ftp anything to this forum and, if you do, it doesn't work. I modified your link so now it opens just fine. Another way to handle photos is to attach them to messages using the Additional options button located below the message composition box (only visible while you're typing or modifying a message).
