Hrqls: yes, you´re right, it is very primitive but it works :) of course it depends on what kind of operating system and browser you are using. (maybe this can be one of the way how to find out how many people are using Bill´s system and IE )
On that page is simple image, size 1024x768 but in HTML code and his size is settled as width="9999999" height="9999999" so when you open the page, your browser is trying to load image of size 9999999 x 9999999 by allocating needed space in memory...and then You need to have some TeraBytes of memory to be able to load that image

Sometimes I am very suprised and scared how your system easily can be attacked.

Here is Html code of page:
<p><img src="pic.png" width="9999999" height="9999999" alt="puh" /></p>
