Bill what he is saying is that the text and banner are one link.
do not close the </a> until after the text
Code:
<a href="http://www.somedomain.com">This is the first line of the text link above the banner<br><img src="http://www.somedomain.com/images/img.jpg"><br>This is the second line of sales text which will be under the banner</a>
I myself would watch the overuse of blinking text. Just because you can do it, doesnt mean you should. And Id put less spacing between the text and banners. Tighten it up a bt and you'll be on your way.
