Layers fading forward and backward

Hello all, i am very new to flash and have what is probably a very advanced question. I am wondering if it is possible to have two overlapping images on a flash page and click a button on the top image and make the bottom image fade to the front. As it is, i have the top image linking to the bottom one by loading another html page, which brings the bottom image to the front. For further insight into what the heck i’m talking about visit my site:

just click the tabs around the outside and notice the various circle come to the front.
thanx for the help-

Hmm…theres a couple ways to do it, but I’ll show you one way which is probably not the easiest way, but it will give you an idea.
Here’s a sample fla, hope that helps. =)

Wow, that worked! i couldn’t figure out how to make the frames stop loading when i published the preview, but the stop layer fixed that, thanks a bunch!=)

no problem, glad it worked for you. =)
