[Feature Request]: Popup images when the cursor is on an image source

[LintaoAmons]

I can hover over the image link using the mouse to toggle the image popup.

Because I use vim mode to write and view notes, so I was thinking if the popup window would show up given my vim cursor is located at the image link.

That's a good idea. I hope you don't mind but I've edited the title to make it more clear for me.
