I think that your problem is that you're probably using IE, am I correct? I was checking mine in FF (of course!) and it was perfect, but in IE, it was all nastily white and a bit cut off at the bottom. I'm almost certain that that's cos IE does something random and irregular with iFrames, but one solution was to change the height up to 85 instead of 70 and add in ' allowtransparency="true" ' just after the height in the <iframes tag>.
So now instead of having:

<iframe src="http://www.imageshack.us/iframe.php?txtcolor=111111&type=blank" scrolling="no" frameborder="0" width="280" height="85" allowtransparency="true">
Something to think of in the next update, Rik©?
