Here is what I do when our kids arrive and download their cameras(or iPod pictures) onto one of my Macs.
Let them go into iPhoto correctly labeled.
But also you can click on the little hard drive icon that the cardreader gives you on the desktop and there are the pictures just straight from the camera.
Then(select all) drag them into a properly named folder, and you have them all by themselves. Then burn them onto a DVD or CD or whatever.
Good example,,,,,,,,,When one of our kids came back from a trip on the Aegean and Black sea and deposited the entire contents of the iPod on this Mac, I uploaded the better pictures(yes it did take a bit of time going thru them, but they were indeed lovely), to Shutterfly and had them printed out in duplicate.

I forgot this, then when you have that folder on the desktop of those pictures that you have separated from iPhoto, then you can do Target Mode, or network your Macs, copy to CD or whatever you want from there on.
These are full versions of the pictures you have in the iPhoto library, all in that other folder. Duplicates.
