I you want to preload images so that the next page in your site will ´load
faster´ then you can use JavaScript.
I used below script very successfully. Just put it inside the <HEAD> </HEAD>
tag.
It really works. Of course replace "yourgraphic.gif" with your graphic
filename (with the quotes).

<SCRIPT LANGUAGE="JavaScript1.1">
<!--
img1=new Image();
img1.src="yourgraphic1.gif";
img2=new Image();
img2.src="yourgraphic2.gif";
// -->
</SCRIPT>

The images are loaded into the browsers buffer and displayed 'immediately'
when needed.

About the 1x1 size. I heard that some odd browsers don't support that and
will always display the graphics in full size. But I don't know which
browsers under which OS. As a matter of fact I don't even know if this is
true.
I just read it somewhere.
Should you know of a system that ignores Height and Width attributes please
let me know.

Sincerely
