In Photo Center it is possible to add several photographers to an image. We use this mainly when we have combined two or more images into one in Photoshop, which happens daily.
However, only the first photographer is actually shown on the site. This is true both for inline photos (see screen shot) and featured media.
This could cause problems for us, since freelance photographers can sue for breach of contract if we don't give them credit when using their photos.

The ability to display multiple photographers on a single image is now available in Sandbox and will deploy to Production on 8/18.
Thanks for this feedback - we'll look into this and address it in an upcoming release.
