Most digital cameras have a 10-sec timer; some even have a 10-sec timer and then take multiple images. That's how DH and I take ours every year. It takes almost no time, it's free and the pictures look great! Alternatively, you can put together a few of your favorite images of the year. Sometimes we include pictures not of us if we went traveling or something (pretty unique flowers or trees, etc).
I recommend using shutterfly.com to print the pictures. They have tons of stock holiday-type cards. We just upload the image, and our address book to the site, and it takes care of addressing and mailing for us. We don't have to look at stacks of the photos or extras left over. I'm sure your family loves to get the photo of you and DH.
