Rows space in images

Hi!. When I activate the pluggin it happens to me that it separates the images, the ones above with the ones below. Without pluggin I have everything together as a photo gallery.
My idea is that the images follow all together. How can i fix it? the same thing happened to me with the plugjet njet pack so they have a reference.

PD: If you see the website, the images will be together since I have deactivated the pluggin until solving that problem.
