I've been using Obsidian for note taking recently, and as much as I really enjoy it - having hypermedia would be quite useful too. I can paste images in Obsidian, but it tends to put the pasted image in the root folder, and I can't display it inline with my notes.
EDIT: VisualEditor, the de facto standard for pasting things like screenshots into your articles seems to be a pain to install. Got my local env up and running though.. Will report back on success with this extension.
I may have misunderstood, but I'm using images in Obsidian without any trouble. Create a folder inside Obsidian, right click it, choose "Use as attachment folder" and then drag and drop / paste images into your documents however you like. It saves to this folder and automatically generates the markup when you put an image in.
I mentioned it elsewhere[1], but conveniently VisualEditor should be getting easier to install in an upcoming Mediawiki release (probably 1.35, which is coming next), because of a bunch of parser centralization work. Fingers crossed, but the hassle that you just went through shouldn't be needed soon.
For those of you looking for an update - I gave up - the steps for installing the Extension were long and confusing on Mac, then found out Obsidian can use different folders for inline items. I wish you could preview it within the page, but that's OK.
