Sending postcard (electronic/maybe real mail) from my photos
It would be a quite a consequent idea to provide a feature (by a photo uploader application) where I'm able to create a virtual postcard from a selected photo(s) with providing (optionally) some "greeting text" plus e.g. selecting a border or some kind of background.
After the postcard is created I'd recommend to be able to share the newly generated image via irista / or on FB via irista.
This idea come to my mind that I seen a lot of people shared his baby / xmas family photo as xmas / new year greeing - why I can not do it directly from irista?
In addition these postcards could be ordered like a photobook if one prefers the old fashioned way. There could be discounts based on the number of postcards ordered.
