Does this exist?

I have two questions really:

1) Basically i have about 50 photographs, which i wish to appear at a spot on
the stage at the pressing of certain buttons. Do i nee dto create an swf for
each image inorder to use an action like loadMovie (which seems a bit
excessive), or is there an equivalent action for movieclips within the main
movie? Such as 'swapMovieClip' or something?

My alternative is to place each image on its own frame in th emain movie and
on th epressing of a button, the movie goes to that frame...i guess that seems
easy enough...i wonder if it will be a huge load time....maybe 50 images isnt
too much.

2) IF there IS a loadMovieClip type action i can use, how do i cater for the
fact that each image is a new size.

Many many thanks in advance,

Francesca

ps) I may be overlooking a very obvious alternative, in which case do
enlighten me :)))
