That wasn't really my intention, (why the oops). I was trying to see how massive a a scroll bar I could make (sadly firefox does not scroll images (hmmmm, or maybe it was autoresizing it to fit on available screen). Also, being a programmer and very much into testing I naturally think of pushing bounds.
Don't worry you didn't break anything. Firefox will show scrollbars if you click on the image which will show it at actual size.
