Today I received a copyright infringement notice from ANP Photo, the Dutch photo press organisation, telling me I was using an image they hold the rights to on this site without a license. And suggesting I pay them 370,56 Euro for the privilege.
The image, that I used in a 2018 blogpost, is this one:

Image: European Space Agency, Creative Commons BY-SA
While ANP, despite its phase of being venture capital owned some time back, is generally seen as a respectable agency, this is a clear and unworthy attempt at license trolling.
ANP Photo contains over 100 million images, and the one above is indeed in their image bank as well, although it doesn’t surface if you use Mars and ESA as selection criteria.
Early on in this blog in the ’00s, I have occasionally used images wrongly and afaik that’s all corrected and no longer the case.
The problem here however is of course that ANP does not have the IP or licensing rights to the image that they claim.
In this site I mostly use images that I made myself, and otherwise use Creative Commons licensed images where the rights holder specifies the types of use you don’t need upfront permission or pay for.
This is one such image.
The image is of the Korolev crater on Mars, so there is no dispute about its source, because no one else had a camera, let alone a human being or photo journalist, in orbit around Mars at the time it was taken in November 2018: the European Space Agency.
That’s also where I got it from, directly from the ESA website, under a Creative Commons license and the clear conditions of having to attribute the image (‘BY’, by attribution, here done by linking and mentioning the source in the text) and sharing any derivative under the same conditions (‘SA’, share alike, here true by default because the image wasn’t altered), but otherwise to do with it as I see fit, even commercially.
If you follow that link to the image, and click on it you’ll see the download link ESA provides for different sizes, and a repeat of the Creative Commons licensing information underneath.
Just posting the image, without me adding links or attribution, would have been enough though, because that is also clearly stated in the image by ESA itself, in the bottom left corner where it says (c) ESA/DLR/FU Berlin, CC BY SA 3.0 IGO.
Even if that CC license would now no longer be there at the ESA web page and had been retracted, it would still mean nothing for this image, because CC licenses cannot be retroactively withdrawn or altered: the license that applied at the moment of use remains always applicable.
That same Creative Commons licensing statement is in the image that ANP holds in their image data base.
So a false claim by ANP, and a very disappointing one too.
There even is a potential argument to be made, a lawyer friend told me, that this image can’t be copyrighted as it was automatically taken without any real time human influence as to timing, angle, composition etc (the camera being on a time delay of 4 to 24 minutes between Earth and Mars after all). But I doubt that argument holds here: I assume the image is a selection and crop of a much bigger image, and that choice and selection probably clears the threshold for creativity in copyright law.
[UPDATE] After I responded to ANP that their infringement claim was license trolling they withdrew the claim, albeit without apology. I followed up with asking if they know how many other Creative Commons licensed or even public domain images they have in their 100 million+ database, given a number of public sources they include for their images, and if they know how many false claims and payments they made and received on those images. I bet the answer is they don’t know (nor care apparantly).
