That's because only the height is being changed; with the width remaining untouched and the height being increased, the image ends up being squished.

To fix that issue, the width has to be set to auto; but then, this causes another issue: the width of image would be too big to fit the width of infobox so the image will appear cut off by horizontal side. You can increase the width of infobox, but the expanding it enough to fit the enlarged images would end up too big and it'd make the layout look rather unpleasant... I wouldn't recommend it.

Why are you trying to make the images in infoboxes huger? The default sizing of them is well enough and free of hassles.
