So my photo library just crossed the 10,000 image mark, and I realized my iPhoto library is nearly 40GB. I recently replaced my aging MacBook's hard drive with a 128GB SSD. With such limited space, I'm looking for another way to store my photos. I'd like to keep some photos (recent ones and perhaps selected meaningful ones from previous years) on the computer, if possible. I'm wondering what you all do with your photos. Do you work entirely off of an external drive? Do you just manually copy photos to an external? I am basically just a hobbyist; I don't need/want anything fancy (read: expensive). Any ideas?
