I’ve been experimenting with a simple imageViewer class, implemented like this:

var viewer1:thumbLoader = new thumbLoader(target\_mc);  
viewer1.loadImage(“whatever.jpg”);

my question is how would i use a for loop to make twenty viewers (1-20) load say, twenty elements from an array. One problem is that if I use a string like [“viewer” + i], the class file is expecting a movieclip and throws up a type mismatch. I would guess it’s done something like this:

for (var i=0; i\<20; i++) {  
var this[“viewer”+i]:Thumbloader = new thumbLoader(“target\_mc”+i);  
}  
but obviously this doesn’t work. any help much appreciated.
