We've collated loads of photos that would make cool photo cards. All the images on Delivr are taken by professional (and really good amateur) photographers and are licensed under the creative commons so you can use them to create free photo cards...
Why settle for some crappy animated clip art for your photo greeting card when you can choose from images as good as these? You can email them to the recipient, post them to Facebook or Twitter or host them on your own blog. Seriously it couldn't be easier.
