DOGLOVER2113  I have almost 2TB's of pictures that I have organized by year. iPhoto is not able to handle that magnitude of images. But iPhoto Buddy does great with it. I have my pictures organized by year. I don't know what I would do without this program. I recommend this to anyone that sees iPhoto getting slow due to large quantities of pictures. To top it all off the program is free and new updates keep coming out. how much better can it be? Writing this to thank the developers for keeping this program up to date and providing it for everyone to use.
