Want to share some research that seems relevant to me - ignore if this is already well known on these threads.
Please see http://www.nyphotographic.com/about.html (text quoted below in case these guys take the page down)
It is quite evident as per his own documented timeline that Youngson started releasing images clearly marked as "CC-attribution sharealike" only after Apr 2015 and even as late as Oct/Dec 2015 presumably not all his images were clearly marked. So if you got his images before say Dec 2015, it's likely that they may have been perceived as public domain.
It's a nuance but an important one IMHO.
Thanks.

Just found lots of my images being used without a license - I am sure these people don't go around stealing things so what is it about images that makes them feel they can help themselves?
July 2015
For those people that insist on using my images without paying I have now released a number on a Creative Commons Attribution Share-Alike license which means they can be used for free as long as certain attribution and license links are provided close to the image, please contact me for further details.
October 2015
More images released on a Creative Commons Attribution Share-Alike license - a lot of people are following the terms of the license but a lot aren't and just helping themselves to the images so to those people don't use my images without the correct attribution or else paying for them.
December 2015
I am spending my days locating my images that are being used without a valid license, emailing people asking them to pay the license fee and most are ignoring me.
I am now thoroughly fed up with this situation so as from now any site using my images without a valid license and being used to promote a service, I am going to pass straight to my attorney to deal with. I can't be expected to spend my days emailing people infringing my copyright only to get ignored or abused so now they can deal with my attorney.
This only applies to web sites being run to promote a service such as legal services, banks, real estate companies etc - people who should know better than to ignore licensing requirements. Often these sites are managed by professional web site designers who are presumably charging their clients for adding my images to the client's sites without a license!
Sites run by individuals not promoting a service will continue to receive an email asking them for my standard license fee of a few dollars.
April 2016
My advisers have recommended I become incorporated so I now trade as a UK Limited company but everything else remains the same - you can see the company details on my contact page.
