I heard about an iPhone app called Printic recently where you upload some photos, and provide an address and the photos will be printed in Polaroid form and sent off in the mail. This was right around the time myself and my 2 sisters each lost one of our cats, so I sent my husband and both my sisters some photos of our beloved cats (along with one of my niece and nephew). I had everyone in tears when they opened the envelopes.
Here are my photos of Edgar, whom we miss so much, and one of Cheeks, my husband's little buddy (who is about 21 years old and isn't doing so well).
I taped them to the wall right next to my desk so I can see their adorable faces on a daily basis.
My sister Jen put the photo of my niece Gianna and her cat Pugley on her fridge.
What a lovely way to send a little something to someone for any occasion. And it's done the old-fashioned way, through the post. Imagine that! :)
