I just found out that Masters is the folder where all your original pictures are stored in iPhoto.
And I have many libraries, and have finally located them all in the Masters folder.
A bit convoluted, but now that I know where the original ones are, I can copy them.
The rest of the stuff on this computer, I will do with Migration assistant.
I have your instructions for installing Snow Leopard, I bought the disk.
So now I have to continue to cull the stuff I dont want on the new computer, thats difficult to do, so much stuff to sort thru!
More questions coming, thank you all!
