Making part of an image glow on rollover

[JesseV]

I'm using a picture as a button. On rollover, I would like a portion of the picture (a light bulb) to light up, maybe with a glow effect. Could any of you point me in the direction of a tutorial that covers things like this, or outline the basic steps in doing it?

Thanks

Ok, that should be what I need to do. I'll take some time tonight and see if I can look at what you did to create it, and somehow make it work with my situation.

Thanks again!
