Topic: Multiple Galleries: variable caption positioning?

I'm building a portfolio site with several different galleries: web, interactive, print, etc. Most images are sized 500px x 500px, captions positioned to the right, with a 10px gutter.

The print gallery will be mostly posters, so the images are more vertical than square. This poses a problem because the image may only be 200px in width, but the caption is still positioned as if it were 500px. So the gutter is ridiculously huge. Check out Work/Print to see what I mean:

Is there any way to force the print gallery to use a different autoviewer.swf so I can adjust the caption? Or maybe a smarter way?

Any suggestions greatly appreciated- I'm running out of ideas...Thanks!
