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:

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