The image within the infobox on http://en.wikipedia.org/wiki/John_W._Garrett is
smaller than the infobox's standard 280px wide. The infobox stretches it
sideways but doesn't stretch it vertically by the same proportion like it did
before the upgrade this week. It appears that the troublemaker is the "none"
modifier in the image tag.
The following code in the Wikipedia Sandbox demonstrates the issue:
[[Image:John W. Garrett.jpg|none|280px|John W. Garret]] <!-- distorted -->
[[Image:John W. Garrett.jpg|thumb|280px|John W. Garret]] <!-- proportional
