Image varification problems

I'm trying to get my image varification to work. It works fine on a mac in firefox and safari but I can't get it to work in internet explorer 6 on a pc. Does anyone have any ideas?

the website is http://rollsmill.co.uk/visitorpage/addentry.php

Thanks

Can anyone else with explorer test this for me.

Thanks

Works fine here in both Firefox 2 and IE 6.

I dont see the image for verification

Part of the problem appears to be your hosts taking this bit of code onto the end of every page sent.

Seems that the image is not being sent correctly as it has the header

Content-Type: text/html

and not

Content-Type: image/png
