All other settings, like colors fonts and stuff like that you
have to change in the STYLE section.

IMPORTANT:
To make this actually show the correct results
you have to place THIS code in all images:
onload="loadIt(1)"

Which means that your image should look  
something like this:
<img src="../whatever.gif" width="10" border="0" height="10" onload="loadIt(1)">
