I don't understand "wts" but do try to be careful in typing
If you're referring to the use of a banner -- basically it's your own visual aid promoting your link; these can be seen by clicking on the Affiliate tab, then click on the drop-down menu Banners to see the samples
If you plan to post your banner, you may need to know where to post it -- there are a few places that one can freely place a banner, mostly this is best on your own accounts -- you can post a banner on some social networking sites, but do be cautious; some places like site forums, discussion boards and reviewer posts ( Youtube, for example ) may not take anyone posting a banner lightly ( they consider this as spam )
