CTRL+z a newly pasted image should delete the link AND the image from Obsidian

Right now pasting an image (let’s say from the web), then changing your mind and using CTRL+z to remove it results in the link being removed, but not the image in Obsidian itself. Manually cleaning those up is tedious.

I propose that if an image is pasted from somewhere and only has 1 reference, CTRL+z should also delete the file from Obsidian.

+1 for this and this could also extend to pasting the same image twice which should keep the same link instead of creating two images in the attachment folder.

Yes, excellent idea(s) - also see Pasting same image twice should not duplicate the image but paste the same link

I absolutely agree. This is what I as user would expect.
