Looking for a good Slide Scanner for my mother's iMac. My mother has a collection of old slides that my late father took, and she would like to scan them and preserve them for posterity, possibly me or the uncle that does the family tree stuff. She's got a G5 iMac w/ Leopard, and is OK with technology, although not a techie by nature.

We have a flatbed scanner for her already, but I am wondering if there is something that will allow her to process a large number of slides quickly and easily, and possibly import them into some sort of catalogue (such as iPhoto, or something similar).
