Pixelfed?

Look into the term static site generator.

You can always make it manually with notepad(++).

Maybe write freely? It's federated and blog format

Hugo is nice if you want extensive customization and you’re okay fighting with Go code and templates, a little bit.

Wordpress as a framework is kinda federated, you can host your own server if you want to.

You can look into wysiwyg website editors, self hosting a website with aws and s3 is wicked cheap, and other providers like netlify are also inexpensive to a lesser degree.

You could check with @MrSebSin@sh.itjust.works, who created and runs https://bellobear.com/ (and posts them on Lemmy to !bellobearofficial@lemmy.world)

What format are you looking for? Something like a comic layout?

Grav CMS?

Idk if this would work but bearblog is a nice platform for releasing stuff. You can customize it a lot and the UI is pretty nice.

I'm hosting writefreely with picsur as the image host for my blog. They're pretty lightweight. Otherwise a static site generator like others suggested.

WordPress can be federated https://wordpress.org/plugins/activitypub/

You need to follow it, but the thing is, you're probably just as well off posting a link from your own account. It comes up as a separate account for me. I don't think the federation there is really worth it

Faircamp is great for this for music - I wonder if it could be pretty easily adapted for art, too.

The answer is probably "no", but.... Any interest in rolling your own? I once wrote a webcomic engine for a friend, and it was pretty trivial: a simple mod_perl script that grabbed a template and substituted a codeword with the picture the client requested.

Nothing fancy and pretty lightweight. My friend uploaded any new comics via FTP and made some minor changes to the template from time to time. It did the job well.
