It's easy to post a ton of photos from your weekend adventures to Facebook, but let's face it: there are only so many people willing to flip through your photos one at a time. Facebook might just have a way to spice things up, though. It's trotting out a Slideshow feature that turns your photos and videos into themed clips that will be easier to watch. All you need to do to get one is take five or more photos or videos in 24 hours -- Facebook will create an initial clip all on its own. After that, it's a matter of customizing the slideshow by adding or removing shots and choosing the theme. The feature is only reaching iOS users this week, but it'll be a big help if it gets friends to check out your vacation gallery.
