Really simple image transition

Hi,

I am basically trying to have my images transition from one to the other inside a movieClip.

Each page of the website I am creating has a banner image which has 3 sets of images inside the movieClip.

I need all 3 images to transition into each other (a simple alpha fade) and I need to have that cycle/loop.

The way it’s setup right now is all my images are in one movieClip and fading into each other, one after the other. It is all linear.

Is there an easier way to transition the images?

The way I am doing it currently is very slow and time consuming. I am up to 3200 frames, my transition lasts for 4 seconds, at 32 frames per second.

Thanks to whomever helps <3
