I guess what you're looking for is an anchored image tag. If you're using an xHTML: <a href="http://banner.url"><img src="path/to/banner" alt="" /></a> If you're using an HTML: <a href="http://banner.url"><img src="path/to/banner" alt=""></a> Note that I've inserted that alt attribute : it's not optional even though it's left empty.
Thanks I needed the HTML for banners when I open a vendor account with Clickbank for one of my sites. So basically where it says, "http://banner.url" you insert your site?
