Responsive Gallery: extra space within border of each image

Hello,

When setting up a FooGallery Responsive Image Gallery, the preview image looks great, but once the gallery is published, there is much extra space within the border of each image (slightly more at the bottom than top; resembles a polaroid). Even without a border; the space remains (uneffected by the size or shape of image or the size of the gutter spacing). I’ve set up a sample on the page linked to above (as rest of site is in development and frequently changing). I wasn’t super pleased with the thumbnails generated for the Justified Galleries (found the deal with those within the forums already), so am attempting to switch to Responsive option, but must get rid of those extra spaces first. Great functionality still, appreciate the hard work.

Thank you for your help!
Alison
