While it's highly unlikely that this is the problem, the 1st one I loaded I didn't realize at first that it's huge, and you have to scroll down and to the right to see the pic.
A huge picture on the screen with in the top left corner a small white square with a red cross in it and for the rest nothing is probably an good indication that I am unable to see the picture. Considering that some can see the full picture is an indication to me that it might be something with the setting of my computer which prevents me from seeing the picture.
