Copy preview, including images, to clipboard for pasting in to other documents

Is there a way to copy the image to clipboard too when copying the content in the preview?

For example, I’ve created the article:

I want to copy the preview content and put it into an email, including the image. But, when I do this the image does not paste in.

Is it possible to do what I’m trying to do?

This works for me! If I copy the image, I can paste it into email without problems.

Hmmm…I wonder what I’m doing wrong, or what is wrong with my computer. It worked once out of 10 tries. Strange. Thanks.
