AS3: dynamically load images into MC

Question

Hi,Currently I have 20 separate png images in the library each made into a MC. So there are 20 MC's, each one holding a specific image for which it is the correct size. What I would like to set up instead, and need some help with, is dynamically loading a different set of 20 images (that I can add to the library), each to one of the MC's. I think that first I would need to create 20 empty MC's to hold one or another of these sets of 20 png's each. What I need help with: how to script this so that 2 buttons could be used: one button would load the first set, each image into a specific empty MC which is sized to hold it (20 MC's total), and a second button to load the second set of 20 images, one each to a specific empty MC which also would be its correct size. I checked out the loader class but this seems to be for external URL's not images already in the library.Any help, suggestions appreciated.saratogacoach

Hopefully you are familiar with how to dynamically add movieclips from the library. You do it by assigning a class name to the movieclip in the library and then you declare a new instance of the movieclip, much like you just did for the generic MovieClip class.

It can work somewhat the same way for adding images. Right click the image in the library and click on Properties. In the panel that opens, access the Actionscript tab in it and assign it a class name. Let's say you name it ImageA. To load it into the movieclip you just created you can use...

var _mcImage:Bitmap = new Bitmap(new ImageA(0, 0));
_mc.addChild(_mcImage);

An mc's size is defined by the size of the content it holds. So if you dynamically create the mc's that should be all you need.
