Use logo as affiliate link?

Hello!

I’m a new affiliate for Bwin since a week and got the question about what banner i prefer. My homepage is all about sportsbookreview so I would like somthing smal with just like the Bwin logo for the link so it does not look like Bwin is sponsring my homepage, is is possibly to solve this problem?

I sent a mail to Bwin a week ago and asked but no answer, hope its easier to get contact with Bwin here at CAP.

thanks in advance
