Hi,
When I go to look in your gallery the one you can't get to work doesn't work for me either - I get a black screen.
But it does look as though they all have the same title but more importantly the pic that doesn't work shows up 3 times with the same name - maybe deleting it all together then uploading it again might help?
If it doesn't you might want to PM one of the admins to have a look at it for you.
