Name: PicCollage
Available for: iPhone and iPad
What it does: Helps you create a photo collage from your library photos, Facebook albums, or pics from the Web (if you're only pretending you took a trip to Africa). You can impress your mother, brag to your coworkers, and make your vacation look even better than it really was, all before you pack your suitcase to return home.
Cost: Free.
What's hot: It could be the fastest way you'll ever find to organize a batch of photos. Create (and edit) a collage of photos and then export the collage to your friends. Also makes gorgeous e-mails and can turn your image into a real postcard (for about $2 in the U.S.). Don't miss the PicCollage blog to get layout ideas.
