Image enlarging in markdown editor in nextcloud 17

Hi all,
I am using NextCloud 17 and I have a question about markdown editor.

I can easily insert the image in my markdown note by dragging the file into my note directly.

And I find the image will be embedded into my note in base64 format.

The question is that the image in my note sometimes is too big to see clearly so could the image be enlarged by clicking the image? or other recommended way to see the image clearly?
