In markdown, I would like to embed a base64 image data uri.

Is there any way to resize the rendered image in markdown?
As per this answer, it is allowed and encouraged to use HTML within markdown. So you can embed and resize a base64 image using the img
tag in HTML by adding the data uri in the src
attribute as follows.
<img width="20" height="15" src="data:image/jpeg;base64, iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg=="/>
