MC rollovers

I’m trying to create a gallery section in a seperate window that is part of my main page. It’s an MC with an instance name that I cleverly called “gallery” I’d like it to be semi-transparent until the mouse rolls over it, then have it fade in to full opacity.

I’ve been able to accomplish this, however, whenever I put any of the clickable pics in the gallery MC they don’t work. The gallery MC still works great, fading in and out on rollover, but the other MCs which are thumbnails that should link to a larger picture, don’t do anything. I know that I have seen this done before so I’m either crazy (which is totally possible) or I’m doing something wrong (even more possible) Any advice???

can you post an fla?
