My MacBook Pro hard drive is almost full and I'm trying to keep videos on an external drive to save space. But I need access to them when using iPhoto (and also iMovie). If I put all videos in a folder I create (say, Videos), how do I tell iPhoto where they are so I can view them in the Library and make Albums and Slideshows with them. If I have to import them into the Library first, then won't they wind up back on my computer hard drive again? Thanks for any ideas.
