You eed to deal with linkages to pull things out of the library, and how that's
done depends on what version of actionscript you are using.
I've never dealt with loading images dynamically from the library, just
symbols (movieclips, buttons). So I can't offer any specific info for that
without doing what you could probably do yourself--research it in the help
files and via Google. That's generally how I solve my own wonderings. If you
turned them into movieclip symbols, then I could help.
