Can't believe you posted all of these boobs and have to get any responses.
Personally I think you should mask all of your aff links with php redirects, whether text or banner.
Just create a subfolder, like "http://yoursite.com/banner", and in that sub-folder drop a simple index.php file with the following code:
PHP:
<?
Header( "HTTP/1.1 301 Moved Permanently" ); Header( "Location: http://youraffiliatelink" );
?>
Then put your banner wherever you want it with the normal code, but change the URL address to
the address of the new subdirectory.
You might also want to add a nofollow attribute to the link. After adding it, your final banner code should look something like this:
HTML:
<a href="http://yoursite.com/banner" rel="nofollow"><img src="(URL of banner image)"></a>
