How do you mention Envato in the imprint of your website?

[flhgmbh]

Hello all,
I work in Germany and here we are quite strict with the imprint. Usually you also have to mention where the pictures come from. Now my question: How do I mention photos that I license from Envato Elements? Is it enough to simply mention “Envato Elements” regarding copyright? Do I have to link the page? Or is there no need to mention Envato in the imprint at all?
I haven’t found any information on this, unfortunately.
Thanks a lot for your help!

Greetings,
Rika

At Elements, you can also download the purchase code for the item. If it’s requested, you could provide the code as well
