@mmmmmm Sorry if my short note upset you.
It is often hard to guess on the question behind the question.
In my opinion because Drafts is crafted to work with text (therefore the tagline “where text starts”)
My native Apple calendar app is also not able to reference photos easily or maybe even at all.
The Contacts App by Apple can only reference ONE image and only in one place. Why not a gallery of photos?
Because it is implemented that way - at least up to now.
Drafts is not and (hopefully) will never be a multimedia tool.
It is though one of the best or THE best application of its kind. I call it a real application in respect to other apps.
Obsidian, DayOne or Pages work nicely with the native photos app because they are implemented and crafted for that. Journaling in DayOne is works like a breeze integrating photos and more.
There would be a point to make that Drafts might implement this but as I argue (and I am only a user and not the developer) every feature brings in a bundle of different aspects that make the app more complex and harder to use.
Greg (the developer) has aimed the app to process text and push it to other places. Many of the users (as myself) are using it as a text database. But some of the features we would really like to see for that use case will never be implemented and that is fine with us.
Other things do heavily depend on Apples idea of the “walled garden”. I say “why on earth” sometimes about this restrictions, but on the other hand: if I hear from Android users about services installed by common used apps and stealing energy from their mobile devices and install notifications like hell I love that wall around every app.
So hopefully we might help you to find a good way to work with Drafts or give you tips about apps that might fit your needs better.
