That’ll be hard to do with Hugo. There’s no way to tell it to use absolute URLs in the feeds only. I’ll need to set up an extra step of some kind. I’ll check it out.

I use a partial in my Hugo theme to replace relative links with absolute links in the content in XML (RSS) and JSON (JSON Feed, ActivityStream) files. It has a regular expression to find and replace all relative links with their abolute version. It’s probably easy to modify to replace relative image sources too.

That’s an awesome approach to combine the 90s web with the IndieWeb, Henrique. I really like your new 90s web-inspired website style, well done!
