I've embedded juicebox within an iframe. On some of the images, the caption is being separated into two lines, and making the bottom line go behind the thumbnails and then unable to be read. Is there a way to extend the length of the caption line, so that it all stays in one line?

I want to keep the caption under the image, rather than do the overlay option.

here's what I mean: http://voelkerart.com/2011.html  look at the second thumbnail, pre(occupied).
I tried using the "max image size" within lightbox, but couldn't figure it out - the first image in my gallery and the second image have the same length - yet the first one shows all the caption, the second bumps it to two lines.

thanks
