If you have any interest in printing your photographs in different ways check these sites out:
Blurb - You can make your own photo book! Cookbook, Instagram picture book, albums, pretty much any kind of book!
PostalPix - Right now this is an app only available on the iPhone for printing out pics. I tried this out, I printed my instagram pics out in a square format - and the pics were great.
My only problem is that since this is available only as an iPhone app and doesn't have a web area for picture uploading, the photos have to stay on my iPhone to use this.
Printstagr.am - Printing out your instagram photos as posters or tiny, tiny books or stickers and some more ways.
Postagramapp - Send real postcards from your iPhone or Android phones.
Keepsy - Print out albums of your photographs. They hook up with a bunch of places including Facebook, Instagram and Flickr.
Easy Canvas Prints - Have any photograph printed on a canvas! You can hang your on photography on your walls this way. Love this idea! I have got to try this out.
My image for the day - the statue of Captain Parker in Lexington, MA. Photo taken with Instagram on the iPhone and manipulated with different iPhone apps.
