Question : W3C validation there is no attribute "border" on imagebuttons.

Ok, I really need help, I've been banging my head against the wall over this for hours.
I can't get my pages to validate.
here's 2 samples:
http://beta.webspider.com
and
http://beta.webspider.com/10-Karat-Yellow-Gold-Aquarius-Zodiac-Pendant_3884339.html
both say that there is no attribute "border".
although during run time on my web server there seems to be a "border" attribute popping up for these 2 image buttons, I assure you there is no such attribute set in my code. I've even deleted all the stylesheets to make sure they weren't interferring. I have no idea where this border attribute is or why it's popping in, can somebody please help? I've been working on this for 4 hours now :( Thanks, Chris.

Answer : W3C validation there is no attribute "border" on imagebuttons.

There seems to be some server side browser sniffing going on... I get a different source when I telnet to fetch your page (no useragent header).

This is what firefox sees:

  name="ctl00$imgInternetSearch"
  id="ctl00_imgInternetSearch"
  src="images/webspiderbuttonInternet.gif"
  style="border-width:0px;" />

... and this is what I see with telnet, apparently the same as the validator sees:

  name="ctl00$imgInternetSearch"
  id="ctl00_imgInternetSearch"
  src="images/webspiderbuttonInternet.gif"
  border="0" />
