It might be hard for you to make a photo album for them unless you have a ton of pictures! But for her, maybe a little keychain with a picture in it? Or a little locket? I guess they are married today! Have you come up with anything yet?
Another thing you could do to show you care, rather than a wedding gift, is get his address from her after he deploys and send him a care package. Or help her make a care package, sometimes it can be overwhelming. I find cake in a jar is a huge hit. HTH!
