http://en.wikipedia.org/wiki/Image:Newtroot_1_0_0_0_0_m1.png (actually it's on commons : http://commons.wikimedia.org/wiki/Image:Newtroot_1_0_0_0_0_m1.png) doesn't display, instead the page shows a big gray square with "Error creating thumbnail: Invalid thumbnail parameters"
"Invalid thumbnail parameters" mean "the image is too big so i won't resize it". As i already commented to Tim, imho the error message should be clearer, as MW users expect an user-layer message. I was told to fill a bug about it, seems a good moment to do.
