Jerry,
Getty did, in fact, specify that images from the set are only available for editorial usage.
Go to Getty's homepage, put your cursor into the search box and type "Berry Gordy Chicago" in the search field, being sure to search editorial images only. This will yield 93 results from that search.
If you click on any of the 93 thumbnail images, you'll be taken to a medium sized preview which will contain the image caption (description) and a host of other file information.
The two key fields to look at are
Restrictions and
Release Information.
For the photographs in this set, the Restrictions filed reads "Contact your local office for all commercial or promotional uses."; this is fairly standard as Getty would be the go-between for the photographer, licensee and image subjects when it comes to getting the appropriate permissions to use an image in either way.
Here's how it works. Getty's client wants to use the photograph in an otherwise restricted manner. Getty contacts the photographer to ensure that they're okay with that particular client using the photograph outwith the limits of editorial use. Getty then makes efforts to contact the person(s) pictured in the photograph to obtain their permissions to license the photograph in a non-editorial context.
It's the responsibility of the client to pay both Getty AND the subject(s) when they want to use the photograph for commercial or promotional purposes.
The only scenario by which this three-way approval process might be simplified is if the subject(s) pictured in the photographs had signed model release forms and provided them to the photographer, either at the time of shooting or at any point thereafter.
The 'release' in the form is basically a written statement of consent that the person(s) have granted permission to the photographer to make use of their likeness in any way he chooses, usually in return for being paid, but sometimes it may be an exchange of services such as "Time for Prints" for instances such as fashion or art modelling.
In all of this, there's one potential spanner in the works: a client of Getty might have purchased an editorial license and then used the photograph in a commercial/promotional context without informing anyone - doing so would be a breach of license terms (a copyright infringement) and also Thompson's rights of publicity.
If this is what happened (and there's nothing in his claim to suggest this) then he's barking up the wrong tree... his suit would at least have to name whomever made use of the photograph in such a manner as a co-defendant; all that Getty would need to do to get off the hook would be to demonstrate that they only ever licensed the photograph for editorial use.
I'd also like to touch on one last thing: assuming that Thompson's claim only relates to the fact that Getty had a photograph of him available for editorial licensing, then he's really going to lose, and badly. I had another quick look around the web to see if there were any other photographers present - and here's an interesting page I found.
http://www.chicagonow.com/ndigo-chit-chat-all-that/2012/11/an-evening-with-barry-gordy-at-history-makers-2/#image/1You'll see that it appears a small red carpet and white backdrop were placed by the event organisers with the apparent specific intention of having guests pose for photographs in this area as they arrived. I've covered dozens of similar events where this has been the case and know the format quite well.
I'll hazard a guess that, when Mr. Thompson arrived at the event, he was invited by event PR to pose for photographs in this very location. It would have been Thompson's right to refuse to be photographed and/or ask where or how the photographs were going to be used... but let's look at the photograph again
http://assets.starsightings.com/photos/000/001/357/00000135723/135723.thumb.160x160.f2d5d654b76505f66d4687c7e75ea1a3.jpg?v=1353420281Yeah, it's not ideal to use a thumbnail sized shot but, if you enlarge it, you can see that Thompson is looking straight at the photographer's lens, is smiling and has obviously stopped to pose for them - therefore, there is implicit consent in having his photograph taken.
Going out on a limb (again), I'll suggest that Thompson objected to the photograph when he discovered it available for licensing and mistakenly thought this was an infringement of his personality rights. If his attorney wasn't conversant with the laws of relating to this, then... well, you can guess how it's going to play out.
