Lightbox Images getting squeezed

Hello, and thank you so much for the work you do!

I am having an issue with lightbox squeezing one of my images, and I can’t quite figure out why. It happens on this page http://www.citytownesonvine.com/details-floorplans/ when you click on the View Floorpan links.

Any help you could possibly provide would be greatly appreciated. I have used all of the exact same settings on other cloned sites with no errors, but this one seems to be giving me trouble.
