Copyright for Song Video

[DEDrummer]

If anybodt can help me, I sure would appreciate it. I have put together a video for Cry Out to Jesus and I want to enter it at the Willow Creek Arts Conference. I need to contact someone who will give me th OK. (I don't plan on selling it or anything, just want to enter it. It includes a couple of pictures from The Passion of the Christ and I have purchased the DVD they sell which includes photos and vodeo clips. the other photos were Goggled and from what I understand, as long as there is no watermark for a copyrighted photo, they are ok. How can I upload it onto this message board?
Again, any help I can get would be appreciated.
