The interesting thing about this is that programs don't seem to be obligated by law to provide 2257 documents for the content they let you use or for the visuals in their promo ads that a sponsor would use. But according to the law
a webmaster promoting a site must have on hand 2257 documents for any of this content that they choose to use on their websites.

It looks to me like affiliates might be limited to using text links for sponsors who do not provide documents for their promotional material if it is going to appear on a website of theirs.

This probably will not sit well with some sponsors, but affiliates here in the
U.S. don't seem to have much of a choice in the matter.
