[DAMINK]

Worked perfectly mate.
Well a few modifications to that code and to the document setup but now its just how i like it.
Thanks for your help.

Spoke to soon.
Seems it works perfectly in Firefox but not in Internet explorer.
In IE the right image breaks out of the max attributes set by the forum where FF does not.
I have the below settings currently.

Document Width = 90%
Document Minimum Width = 900px
Document Maximum Width = 1200px

With the below for the banner code.

<div style="width:100%;">
    <div style="float:left; width: 400px;">
        <a href="/test"><img src="./images/left.png" alt="xxx" /></a>
    </div>
    <div style="float:right; width: 200px;">
        <img src="./images/right.png" alt="xxx" />
    </div>

Any ideas on how to sort it out so IE can show it correcly?
