With Halloween coming in a few weeks, Smilebox, a photo sharing app for the iPhone, is adding a special collection of spooky stickers (e-stickers?) and captions for customization. All of the material is of the cute, family-friendly variety, so this is grade-A material for sending silly pictures of your kids to friends and family, just for the sake of doing it. As an added feature, you can have the app send you a Halloween collage of all of your seasonal pictures that you took, or of just the pictures you select. The Smilebox App is free on the iTunes App Store now.
