I've been playing with it abit and found that I can burn, easily photos from iPhoto to a CD. It's quite easy.
I wanted to burn photos from an SD disk to a CD, but iPhoto doesn't recognize it as burnable. I guess the photos have to be imported to iPhoto first. Actually, it isn't a problem since I've already done this. I just don't know exactly where all those photos from the SD disks are on iPhoto since I've cataloged them in various albums. But again, it doesn't matter. I'll just burn a bunch of albums that I really want to archive to a cd. I like your idea of a rewritable disk. I'm always tweaking this stuff.
