Out of curiosity I just made two images:

15,000 x 15,000: http://i.imgur.com/WzCyE.png

50,000 x 50,000: http://i.imgur.com/kgmHu.png

Both FF and Chrome refuse to open the second one. IE does something weird. Both Opera and Safari figure out the size correctly, but don't display the image.

With Firefox (15.0.1) I get some really, really strange results with the second image.

When I opened it the first time, or everytime I press Ctrl+Shift+R it works, but it shows the URL, and a litte icon in the upper left corner: http://i.imgur.com/B7jFE.png

If I press F5 or Ctrl+R it doesnt work, just as you said.

Wow, the first one crashed my chrome browser. Thanks for sharing

In case safari crashes and you won't be able to open it, sudo rm -rf ~/Library/Caches/com.apple.Safari did it for me.
