Which uses more memory - Import as Control vs Referenced Control?

[Stgoldberg at aol.com]

I am trying to decide whether or not to   use "Import as Control" or 
"Referenced Control" for importing jpegs into a Revolution program.   On the one hand, 
I'd like to avoid putting out a standalone program with a separate folder 
containing all of the pictures (Referenced Control), but I'd also like to 
conserve disc space for the standalone application. I understand that "Referenced 
Control" simply uses the same photo repeatedly without taking up extra memory for 
each time the photo is used.   Does "Import as Control" take up additional 
memory each time the same photo is duplicated in the program?   Thanks.
