New to Tiger, I am still retaining a Panther OS on another volume. I found that I can place an alias to my iPhoto Library folder that resides in ~/Pictures on my Panther volume into my ~/Pictures folder on the Tiger volume, and it works correctly, at least for now, when running iPhoto while booted from my Tiger volume. I added another folder of photo images to see if it would show up in the iPhoto Library back on the other volume. Indeed it does. Everything seems to be OK, here, but of course, YMMV.
