Is it possible to change panel opacity dynamically in presentation mode?

    Jul 27 2013 | 9:39 am
    I am working on a graphic score and I want to grey out each page (JPEG) as it's finished. I thought I would have a panel over each page and change the opacity after it's run it's course. Is there a way to do this, or can anyone think of a better way of greying out a JPEG?
    Many thanks
