Align Center

@irinasopas – This is the most commonly used custom CSS to center a Basic Thumbnails display (I wouldn’t recommend using an h2 element in the manner you are for this case):

/** Center Basic Thumbnails */
.ngg-galleryoverview {
    text-align: center !important;
}
.ngg-gallery-thumbnail-box {
    float: none !important;
    display: inline-block !important;
}

Thanks!

@irinasopas – More often than not that would be styles from the theme, have you contacted its author for assistance on that?
