Hi there… I’m not new to flash, but pretty new to AS3.

I’m trying to create a grid of 40 images that randomly fade in and out at different intervals. so at any point in time, some images will be at 100% alpha (or 1), some will be at 0, some will be anywhere in between (.1 .2 .3 .4 .5 .6 .7 .8 .9) I’m sure I could figure out how to randomly set the alpha of one image, but I’m not sure how to set random alpha (with tween) on a random image.

Also, at first I was going to import each image into flash individually, but then I though it might make a smaller file, to pull one large image with all 40 images, then just have a “whitebox\_mc” placed over each image that fades randomly to expose the image below.

Help is greatly appreciated!!!
