Massive spacing around portrait images|

Hi there!

After updating WP and the plugin today, the spacing around images in my image galleries got alot bigger, so much it looks weird. It only appears around portrait format images, landscape are fine/the same as before. Check the link and you’ll see the problem.

Is there any way to fix this?

Best regards, P?l, Norway.
