Flip-x problem with sizing

Hi! I have a problem with sizing on the flip-x setting.
I have already resolved the issue of my images not having the same size thanks to another post on this forum
However now when hovering over the images, you can see that the size of the info is not completely covering the photo, but only half.
Can you tell me how to resove this?

You can see the problem over here: http://ismsbelgium.be/index.php/team/
 
 
Thanks!
