I've had many well-intentioned but ultimately abortive attempts to get on board with Emacs.
So, are images 'possible' or 'trivial'? Not trolling, and I do note that you say it's not part of your workflow.
On the other hand: no, Emacs is not a WYSIWYG word processor. The need to support terminal as a display backend weights heavily on the pace of GUI improvements. That's because all interface elements need to be renderable on all backends (not strictly true, but the prejudice against GUI-only elements is significant). So if you hope to be able to easily and conveniently display something like this: https://klibert.pl/statics/vw-doc-view.png then Emacs is empathically not the best tool for the job.
so (out of the box) in org mode if you type [[./file/path/to.png]] it will turn into a link, if you hit Ctrl-c-x-v it will toggle between showing images as a link (which will open in a new emacs buffer) and just showing the images inline.
ALSO you can just drag an image file onto an emacs window and it will display it in a new buffer.
however getting it so that A) images are displayed automatically when you finish typing the [[path]] and/or B) dragging an image into emacs will result in a new link in orgmode... that's probably possible
This is the package you're looking for. Just drag and drop images into the org mode buffer and you're done. I've been using it for years to take lecture / book notes in org mode where I have to constantly take screenshots and embed them in my notes.
part A is still annoying though. if you have inline images toggled and type in a new image it still turns into a link instead of an inline image.
