try making each seperate .jpg on a .swf if u use the loadmovie part. then make a MC where you want the movie to load. (top right corner is usually the best place for them.) then just have a button loading the .swf with whatever jpg. in the .swf with the jpg in it, make an alpha tween. then for 3 buttons to load 3 swf’s. make it this for 1 of them then repeat for the next 2 changing the names.
on (press) {
loadmovie(“jpg1.swf” , “_root.NameoftheMCwhereyouwantthejpgtoload”)
}
