Hi this is my first attempt at powerpoint and I am using 2007 version. I have a picture of the pastor of our church. I have managed to create a halo on as a transparent gif and placed it over the shadow of his head. What I would like to do is make it sparkle a bit as it is not obvious. I can save the transparent gif as a separate image if this would help. Any ideas for a novice like me.

TIA

Desmond.
