My wife and I have started a small photography business. I load all our pics on my mac in iPhoto. We run through them and delete any bad shots, then I burn a copy for her to edit in photoshop on her pc. The problem is I have so many photos that I am running out of disk space on my mac. Sure, I load clients photos to my external drive when we're done, but I no longer have the luxury of scrolling through thumb nails if I want to quickly retrieve an old pic. That's why I want to know if there is any way to link iPhoto to my external hard drive? From what I've seen, I can't. But maybe someone knows a trick. What do you guys to who have several thousands of pics on your macs?
