I've noticed that when signing up to promote sponsors via CCBill that some recommend adding extra code starting with "&HTML" after my ID number in the link URL that will take the surfer to a preview page or free model gallery. For the ones that don't mention this, my affiliate link goes to their age verification/warning page.

Here's my question: can I go ahead and add the html link on my own for all my sponsors that will take surfers directly to the preview or free model page? Or could this screw up my getting credit for a sale?

I'd like to get surfers as close as possible to the sponsor content that will convert them but I'm worried about modifying my affiliate link and doing something that will lose money for me. Rather than emailing each sponsor I thought I'd ask here to see what others do.
