I don't it's possible really. For example, Canva sells a big volume of extremly low RPD licenses without telling us which ones.

In addition to the problem of getting totals, with royalty free licenses, you have no way to map total downloads to total uses. One license could mean many hundreds of uses if it was a large company using the image in many ways over a long period.

With rights managed licenses, you can answer those sorts of questions, but I'm assuming you are licensing RF, not RM.

Also, for them to copyright or get a registered trademark for their logo, using work that was previously licensed as RF may pose legal problems.

You would think but the sites negotiate these deals frequently.

I have sold rights under similar circumstances through 123 and SS among others. In one case for a very near 5 figure sum for an image that had licenced many times and was a few years old. Lord knows how much the agency got because that was just my cut (you don�t get to see the figure the client paid).

I always make sure the buyer is aware that the images have been licensed and can be used by previous buyers in perpetuity and the agencies have always said they are. All they ask of me is that I remove the image from sale ASAP. I would be wary of setting this up this kind of deal myself for this reason too.
