Can't see image in post

I have looked at this thread on 3 different machines with 4 different browsers today, and I can't see the image on any of them. One machine was a Mac running OS X using Safari, a PC running Vista with Firefox & IE and another PC running XP with Firefox.

I either get nothing, a box with a little red X in it on my PC, or a blue box with an X in it on the Mac.

OK, as soon as I posted this, I went back and rechecked that thread, and the image came up...
