Side Image Section

The "Side Image Section" used as standard content widget shows an image on the left side of the content area. If the viewport becomes smaller, the image leaves the viewport.
The image is only as high as the content. You could use "Is fixed Image Size" to force the image height to the original height of the image source.

Side Image Section in a tab

The "Side Image Section" used in a tab could be set to show the image in it's original size because the tab cuts overflow content.
You have to set the tab content width to "Full" and you have to enable the "Is fixed Image Size".
The inner content width should be set to medium or small in this case.
