Transparent PNG (24) issue in IE8 and below using jQuery Cycle

I'm using jQuery cycle to fade my slideshow in / out.

My slides have a background, and their are semi-transparent PNG's (using tag) within my slides. While the slide is fading in, the semi-transparent areas have black splotches. These splotches disappear after the slide has fully faded in.

I've gotten around this sort of thing using using AlphaImageLoader within the CSS, but these cannot be background images.

Any thoughts? If needed, I can setup a demo.

Thanks in advance for any help!

I've simplified it and uploaded an example here:

What is happening in your application is that IE7 is applying the alpha filter to your PNG, and is then asked by jQuery to apply another alpha filter for the fade. This has visible results like you said.

The way to get around this is to nest your png inside a container and then fade the container.
