Bar covers photos

[threez]

Good morning everybody,
I'm trying to create a photo gallery but I stumbled in a problem. After the creation, when I select one photo, I can't see it entirely. I mean, there is a grey bar that covers part of my picture but I can't understand which function should I disable
Here is the pic

Hi, do you get this problem when testing another template? When you test it with other popup method, do you get the same problem?
