I've had a lot of trouble with iPhoto, most of it my own making. After careless moving of photos and backups, I've now FINALLY found all my images and gotten them back into iPhoto. iPhoto is open right now, and I don't dare to close it until I'm certain that all these photos will still be there next time I open it. I've apparently had more than one iPhoto library (and most likely still do), but the images in the program right now are the ones I want to be my library. Can I just close iPhoto and know that they'll be there next time? Should I export them to a folder on my desktop (for example), and point to that / import it the next time I open the program? Ideally I want my iPhoto library on my external HHD. I've made a real mess of this, and want to clean up once and for all.
