Writing a blog post on #Nostr. Are there openly-licensed Nostr images that one can use?

I'm new to Nostr, but working on a blog post about it.  Given my reach in the web community, I'd like to include a basic comparison with ActivityPub. I want my comparison to be fair and balanced and would appreciate any feedback that you may have.  🙏🏼 Screenshot with my current draft:  https://void.cat/d/Y8pohSxZEv16Y6BLGVPv5G.webp.  #nostr #activitypub /cc #[2] #[3]
