Sheeeeeeeesh.. if I click on both I can see them but they just dissappear again. Grrrr.. Pics have not been posting good for me lately..
I think certain websites pictures might "time out" so to speak, if pix are lifted off them. Not sure that's what's happened with yours but I've had similar experiences with others.
Or it could be the evil cyber gremlins at work. That's probably it.
