Steven,

The gallery is not yet on the Internet pending resolution of this problem, so I can't send you a URL.  I don't see any way to attach an image to a forum post, so I have sent you a partial screenshot showing part of the bottom of the image down through the tops of the thumbnails.  The space to which I'm referring is larger then the thumbPadding setting of 10, and I would not want to set that to 0 because, as you wrote, it would remove the padding from all sides of the thumbnails, not just the top.

I set the caption below the image and max caption height = 35, so I just have one line with the file name and n/nn.
Thumbs position is bottom.

How can I delete the vertical blank space between the bottom of the caption and the top of the thumbs?  Similar to the Juicebox Pro API Demo at http://juicebox.net/demos/support/api/ except that my caption is below the image.

Thanks.
