Oh, that is strange! No pics showing here, although Bev Hall's pic posted by Geriaviator on the same page is. Unless others can see them, I can only suppose that they are only showing to you because they are already in your computer anyway. Try logging off, then back in?
The only way that others on the internet can see them is if PPRuNe displays them from the images' internet address at Photobucket, or wherever. You need to check if that is their image location (right click copy location with the mouse pointer on the image and then post it into your browser address window).
Good luck!
