Well it seems like Flickr is out to get me this year. Have a look at this two pictures of the same group pool and you can see the picture I uploaded is strangely invisible to people who are not me. I have checked every possible setting, the pictures display fine elsewhere (like here) but when I add to them to a pool they vanish. (look between KlausTheBest and johopo(John))

Well, I certainly dont get it. Any one who has any idea of how to solve this please let me know.
