Only, I couldn't for the life of me remember how I had done it, so after some fiddling with the pie shape and "pasting in" I started a search on the internet only to find that my earlier attempt has been used as an example here: www.dmxzone.com/go?11409 .
Hélas, the promised tutorial is not there (anymore?) The "let’s look at the process used to fill the pie-shaped wedge with an image" piddles out into empty space.
Can someone help me to get me back on track?
I am using FW CS4 now. Unfortuanately I no longer have the original png's.
