Roundaboutly everything a business does is advertising, I'd draw a line between commercial advertising (ie: paid ad placements, physical displays) and content only available by someone actively going to a photo gallery on the website. "You retain your rights to any Content you submit, post or display on or through the Services. By submitting, posting or displaying Content on or through the Services, you grant us a worldwide, non-exclusive, royalty-free license (with the right to sublicense) to use, copy, reproduce, process, adapt, modify, publish, transmit, display and distribute such Content in any and all media or distribution methods (now known or later developed). Tip: This license is you authorizing us to make your Tweets on the Twitter Services available to the rest of the world and to let others do the same." That's pretty explicit, you don't have total control over it once you publish that photo, neither according to the policy nor in a practical sense.
