tiki-top_bar.tpl is the key.
The best thing to do is delete all lines in there already and just insert something like:
<img src="one.gif" />
<img src="two.gif />
<img src="3.gif />
<img src="4.gif />
<img src="five.gif />
You can leave the div out as well. take a look at my http://damosoft.co.uk site, everything from the black banner bar to the background and the tux logo, jabber status icons is in the tiki-top_bar.tpl
If you get stuck, copy/paste your top bar contents here. remember to surround it with the CODE plugin!
