If you’re looking to send your baby snookums photo love notes this Valentine’s Day, Valentine Photo Free (iTunes link) is a simple app that makes adding hearts and other Valentine’s Day-themed graphics to your photos easy. And best of all, it’s free.

While not the smoothest interface we’ve seen in an app, it gets the job done. Simply drag the graphics into the photos. You can resize or rotate the graphics through button controls or pinching gestures (we recommended using the buttons as the pinch gestures don’t work too well here).

When you’re done, you can save the finished product to the iPhone’s photo album, email it, upload to Twitter, or upload to Facebook, all within the app.

Again, it’s a very basic app with a lot of limitations. For instance, it doesn’t support landscape photos, so you have to choose only sections of landscape photos to use. And you can’t add your own text—you have to use the graphics provided. But the graphics are not too bad.

Valentine’s Photo Free is a free download from the iTunes App Store.
