@taseroth Just to be sure, there is a vibrant #Antora community via https://antora.zulipchat.com/ where the core people are very responsive and helpful in either how it can be done, or why it doesn't fit the design concept 🙂
I would write a page as `pages/topic-a.adoc` and put page-specific images under `images/topic-a/image1.png` etc.
Also because so far the Intellij Asciidoc/Antora plugin I use does a great job at updating (refactoring) sources and references when renaming things.
