Gallery: Get the first image link / path from an album

Hi,

I'm converting an existing static site to Perch and one of the things they use is a prebuilt javascript library for the slideshow.

I'm using the Gallery addon as it's the most sensible way to manage and generate the slideshow.

I need to be able to reference the first image from a given album on the 'click here' link that starts the slideshow.

Is there a straightforward way to get the image link / path?

Thanks,

Alex
