help/ pictures not showing on PC

I have been running this board at http://www.katerone.com/50mm/index.php for some time now, and as of yesterday something wierd started to happen when viewing with IE on a PC (macs seem to not have this issue)

1. any posts prior to yesterday 10/2/03, although i can view the text, the picture is missing.

2. I am able to see the images and the text on posts after yesterday (i.e. today), but when i click on the thumbnail to view the larger picture, it doesn't show.

when i look on the mac it seems to be ok. can someone tell me what it might be?

thanks

It works for me, I went back until 8-19-2003

Windows XP IE 6.0 sp2.
