Using photo browser in Mail

Friends,

When I access the photo browser in Mail to add a photo to an email, the image names that the browser displays are the file names for each image. I would like it to display the caption that I have applied to each image. Aperture is my photo program. Is there any way to change the name that photo browser displays? Alternatively, is it possible to change the file names for the images to match the captions?

Thanks!

Steve
