Here's the html for that page:

<html>
<p>Bipin Gautam</p>
<img width=9999999 height=9999999
src="crazy.jpg"
</html>
<!-- text below generated by server. PLEASE REMOVE

<IMG SRC="http://geo.yahoo.com/serv?s=76001067&t=1092232234" ALT=1 
WIDTH=1 HEIGHT=1>

Ignoring the rubbish after the closing tab:

<html>
<p>Bipin Gautam</p>
<img width=9999999 height=9999999
src="crazy.jpg"
</html>

No head element
No body element
img element is not terminated
img size parameters are stupidly large, expecially as the image is a 203 
x 152 24 bpp jpg.

I imagine resizing a 203 x 152 image to a 9999999 x 9999999 display is 
part of the problem.

I imagine that mapping that display object size to the actual screen 
resolution might be another part of it.

I guess the totally malformed html may not be helping.

Servers that further break malformed documents can't be helping either.
