Soon after I uploaded my SG-1 / Mr. Gordo manip I decided that I'd made the pig a bit too small and uploaded another version. For some reason this is showing up fine on computers that aren't in my immediate vicinity, but I'm still seeing the original version here.

So - a quick poll, which may help to track down the problem. Take a look at this picture:
