Kbin magazine's image is squished. Not a CSS issue.

Before the latest kbin UI refresh there was an issue where the magazine logo's aspect ratio was altered and the pictures looked squished, but that was easy to fix using some CSS.

But now after the latest update the issue is in the image element itself; so now the logo for my magazine which I uploaded as 600x600 is served as 500x600 and then resized using CSS to 260x260. Nearly all magazines I've visited have this problem.
