[DM-MUG] iPhoto and mounted discs

[Darcy Baston]

Have you ever noticed that when you insert a CD/DVD that has an  
iPhoto library burned to it, it mounts automatically in iPhoto so you  
can browse your current library and the mounted on?

I'm trying to simulate this so I can have multiple libraries be  
accessible from within the iPhoto app. I can't make it work. :)

I've tried:

-used Disk Image to make a disc image, and copied an entire iPhoto  
library into it.
-used Toast 8 to create a disc image, that mounts like a CD/DVD with  
an entire iPhoto library on it

Does anyone know what iPhoto adds/changes when the 'burn' feature is  
used so that a mounted device gets analyzed for content?
