How can I transfer pics from one iPhoto library to another iPhoto library, without having duplicated the space on the harddrive?
Will the space (GB) duplicate when I copy the pics from one library into the other and delte the 1st one or will it stay the same?
I think this is likely what you want...
When done you should occupy just one space, but be sure you have a backup if it's important.
