Not yet, but I made a plug-in a while ago to use your WordPress as a media host:

GitHub

GitHub - fabianfabian/nostr-media: Nostr Media Uploads for WordPress

Nostr Media Uploads for WordPress. Contribute to fabianfabian/nostr-media development by creating an account on GitHub.

Should not be that difficult to change it and also allow all you WordPress users to login with nostr. I might give it a try but I'm working on some other things first.
