Upload image from URL

I often take image snapshot which generates URL to the remote image (such as https://myimage.somesite.com).

If I insert this image, I get URL link so to see the actual image, a person has to click on the link.

On the other hand, to insert such image, I have to go to that remote site, save image, then upload it again as the local image.

Is there a way to implement a feature to pull image from the remote URL and embed it as image?

This is a usual feature on all forums. Check StackExchange sites for example.
