I have been scanning old family photos at high quality resolution which takes my scanner about 4-5 minutes per scan. So to save time I am scanning 5 or 6 photos at a time (they are quite small, as old photos tend to be). Here's my workflow: I take the huge scanned image file with 6 photos and I duplicate it 5 times on my desktop. I then import all 6 copies to iPhoto (clicking "yes", I do want to import them even if they're duplicates). Then as I browse this set of imported files in iPhoto I edit each one by cropping to a different photo from among the 6. I also make any adjustments at that time. I end up with an iPhoto folder containing what looks like 6 separate photos. But behind the scenes iPhoto considers each photo to "really" still be the huge multi-image file, each with a different crop area. Each photo as cropped down is a few MB. But along with each finished photo iPhoto is storing a huge (~30 MB) file. Is there a way to get iPhoto to discard the huge file and just keep the cropped versions as the only copies? I'm not afraid of losing any data, as I have a copy of each of the huge files. It's partly an issue of memory and partly that I'm afraid I'll accidentally undo any editing, and revert to the huge multi-image.
