Center aligment isn't working good

Hello!

First, thanks for this module :)

I found out that when centering a resized image it doesn't really center the image as the container size is different than the image styles defined. https://monosnap.com/file/9BNiwyWLIbqKNiILKOZKCqy2jaAcHb
So the image style gives a width 500px, a container - 447px. margin-right: auto; and margin-left: auto works for the container, but the image still is 500px, which makes the image positioning more of the right side.
