Lightbox for images not showing up right.

If you click on the image to enlarge it on the avia gallery main page it doesn’t come up right it shows up all the way on the bottom of the screen. also, when clicking into an image it is adding a lot of space on the bottom of the images. Unless I add this code:

#top div .avia-gallery .avia-gallery-big-inner {
height:125px !important;
}
}
.responsive #header .social_bookmarks {
height: auto !important;
}

#top .social_bookmarks li a {
height:30px !important;
}

#top .social_bookmarks li {
height:30px !important;
}

#top div .avia-gallery .avia-gallery-big-inner {
height:460px !important;
}

Had to add all these codes, because after updating all the images were acting weird.
