LordWeirdo, you may not have noticed that the background has the same color as the image itself, which only has about a third of the infobox's width.

This is the CSS being applied to the image: .portable-infobox .pi-image-thumbnail { max-width: 225px; height: auto; } If you want the image to be "at least 300px height (max 500px) with proportional width," I believe you would need something like this: .portable-infobox .pi-image-thumbnail { min-height: 300px; max-height: 500px; width: auto; }
