@b_cavello my mistake, sorry!
If I were to use your picture as a banner, a) I'd want to declare your authorship, as a respect thing and also as a "look, there's good stuff, check out B!" but also b) if I use other people's stuff they may get snarky that it was not meant to be used thus. So in that picture you could include (as subtle or as loud as you prefer) your name and a date, or a link to you? Or you could embed one of these, if you prefer: https://creativecommons.org/choose/
