Issue with an image displaying

[Spartan198]

There's some kind of problem with the Schmidt-Rubin Model 1911 image on its page.

http://www.imfdb.org/wiki/Schmidt-Ru...bin_Model_1911

The image of the rifle itself won't show when the size is changed to 600px. It works at 650px, 500px, and 450px, but not at 600.
