Changing the first ME picture shown

How do I change the first picture shown on the screen during boot up? Windows ME starts up - then shows a picture - then goes back to booting up and finally comes up to the desk top.

What is this picture called. I don't think it is called wallpaper but then I don't really know.

I had a Christian program in there that changed the picture with scripture each time I started my computer but I had to format and lost it. Now I don't remember where I downloaded that program.

Any help would be greatly appreciated.

Thanks,
Jan
