i recently used "Touchnote" to send postcards with my own holiday photos.
you can upload and send postcards from your iphone while on holiday.
touchnote prints and sends the postcards from australia/uk/us and so they arrive 2 days later.
prices start from AUD 1.24 to AUD 0.99 depending on how many credits you buy.
i have no affilliation to this company, used them to send postcards home last trip and very happy with the quality and timeframe.
search for it on the app store.
sherbet - posts with an australian post mark - but at least they arrive before you get home!
