Very strange thing - Guru required

Ok I will try and outline a particular problem I had recently!

I would classify myself as being reasonable compentent with HTML but recently came across something that really perplexed me. i am currently playing around with building online stores using cgi. Anyway I recently discovered that only half of the people I wanted to could view the site pictures I was displaying. I called a friend and asked him to view for feedback I was shocked when he said he only got red xs and alt tag descriptions showing. When he disabled his firewall he could see everything???? How in hell does a firewall prevent people seeing jpegs and gifs on IE6 service pack 2??????

The page in question is http://www.butthatsnotall.co.nz/store/agora.cgi the images are currently serving from http://www.butthatsnotall.co.nz/store/picserve.cgi?picserve=/
but when the were served out of an ordinary old images path I got the 50/50 view problem?????

Has anyone got any ideas why a firewall was crippling accessibilty??

Cheers in advance
Alex

I've heard of some Firewalls blocking images that appeared to be ads -- needless to say it seems they aren't that good at it, since some people can't see normal images either.

Just a shot in the dark; I've never had this problem myself.

interesting...these were just ordinary product shots not really full on banner ads or anything...have been asking around locally and never came across this one before...and its just this particular site.

The firewall probably has a setting that will refuse images that are being served dynamically. That's usually not a problem when they're coming from the same domain so maybe the default is set a bit to restrictive on that one.
