bottom space missing|Tweet Like Plusone and Share Plugin|Plugin Support Forum|TECHXT

I love your plugin, I use it a lot, mostly without any style changes. But here I need some changes and I cannot figure out why the bottom is missing? : http://picture-your-day.com/

I have this in my stylesheet, bacause images have a border in this template and I wanted to center the icons.

iframe,

.social4i img {
border: none !important;
}

.social4i {
padding-left: 96px;
}

thanks for any help
