You've undoubtedly heard the old expression, "A picture is worth a thousand words." But what if you combined the two? That would be even better, wouldn't it?
Well, thanks to the marvels of digital photography, sound recording, and smartphone technology, you can do just that. One way is through PhotoVoice, an app that allows you to take a photograph with your iPhone, record and attach a sound file to the picture, preview the combination, and then send it via e-mail, SMS message or social media sites like Facebook and Twitter. Or, you can do all of those things in quick succession. "For the first time, your iPhone photos can talk!" boasts the app's page in the iTunes store [source: iTunes].
Aside from the cool stuff you can do with PhotoVoice -- creating talking digital birthday cards, for example -- one of the other interesting things about the app is that it wasn't conceived by a professional smartphone software writer, or even by a photographer. Instead, it was conceived by Dan O'Day, a radio industry consultant, who was surprised to discover that someone more technologically savvy hadn't thought of it first.
