Allow image insertion through URL

[cilerler]

As a user, I would like the app to support inserting images through URLs.
This would make it easier for users to insert images from online sources.

I think this is a great idea. There should be some sort of modal popup where you can drag and drop images or click it to open the file manager. And below that some kind of input field where you can type a link and it will open it as a preview on the drag and drop place.

Something like this:
