Believe it or not, none of the actually Portable Infoboxes has been deployed yet. So Column is the original wikitext infobox.

I've adjusted Column just now (in the wikitext) to explicitly set images to 300px, which should help. Portable Infoboxes autosize, so this shouldn't be necessary once it's migrated.
