I am new to this business hope someone can help me out. I have an affiliate capture page. i am purchasing a domain and using URL forwarding so that i can promote the affiliate site without the long extension. Anyway, what i was trying to figure out is this. i am using a traffic exchange to help promote the affiliate site. Is there a way to also promote a banner from the domain site (it is also an affiliate setup)? They will provide me with the code for a banner. I don't know how to make that work because the traffic exchange wants am image URL and a site URL. I have the site URL but don't know how to get from the banner code to an image URL. Can anyone help??
