existing photos on external hard-drive becoming iPhoto library?
I have an external hard drive with thousands of pics, takes up way to much space to store on my macbook air (2011). I am trying to understand how to keep these photos stored on the external, yet make this my iphoto library source. The key here is that I do not have any photos currently in iphoto (or stored on my macbook air), so this is not an issue of clearing up space on my internal hard drive. thanks for your help.
