[Plugin: NextGEN Gallery] Gap between caption and thumbnail

Does anyone know how to control the space between the bottom of the thumbnail and the caption for the gallery-caption.php template?

The space is too big in my gallery, and I can’t seem to find anything in the CSS to control the height of the thumbnail-box. I tried putting in a fixed height, but it just makes the box smaller but the gap remains the same.

Thanks for your help…can’t seem to find this problem addressed anywhere…
