Here's a quick tip for the Holiday season: printed greeting cards are a Holiday tradition, and using Fotomoto it's easy to offer your images as greeting cards.
To get started, add a few of your favorite Holiday-esque photos to your Fotomoto-enabled site, and make sure they are in a Collection that has Cards enabled (see this article about setting up products).
Now you can promote the new images via email, your Blog, Facebook, Twitter, or all of the above.
