Would highly recommend photos. Browsing gaming chairs, for instance, I immediately bounced from the page because I couldn’t visually browse the content.

Amazon has an affiliate program that allows you to generate banners with embedded images.

This seems like an appropriate license since he's linking to amazon anyways.

Maybe rights issues?

[chrischen]

He probably just wants you to click to activate the affiliate link.

EDIT: Doesn't seem like the Amazon links are affiliate links, even though he makes a statement on the page that he's trying to make money.

Showing photos would fall under fair use.

Citation needed.

Any case, fair use is a defense, not a license or permission.

[wolco]

Clearly a fair use situation.

"the fair use of a copyrighted work, including such use by reproduction in copies or phonorecords or by any other means specified by that section, for purposes such as criticism, comment, news reporting, teaching (including multiple copies for classroom use), scholarship, or research, is not an infringement of copyright."

[TylerE]

This is commerce, though.

And again, Fair Use is a defense. It only kicks in after you have been sued and are in court.
