Ok, if I drag the image at <http://skunkworks.macheist.com/declass3b.jpg> from Firefox to my desktop, it's dimensions are listed as 20597 x 19868. And I can't open the file. But if I save the image using the menu, I get dimensions listed as 1000 x 1000, and it opens in Preview.
2059719868 looks like an IP address to me (22.214.171.124 -- which is registered to the US Navy). I might be barking up the wrong tree here.
The pen is mightier than the sword . . . unless the pen is a BIC.
