You need to look who posted it. If read above, it indicates that a photographer posted the photo and they are not going to know the answer to any of your questions. It's pretty simple.

Maybe it is not pretty simple to everyone Mary Thurman. But I suppose you are the type of person that cannot help themselves from responding just to throw in a pretentious passive aggressive comment for all of us stupid people that are less technologically inclined. If your comment is condescending instead of kind and helpful then why even comment at all? The world would be a better place

Tile is from Cement Tile Shop, Mexican Contemporary Collection, Burgos pattern. They don't show it in yellow, so it must have been a special order.
