Hi!

I'm trying to make an animatied text overlay ontop of an image.  Looking
through the helpfile I find lots of backgroud properties to play around
with, like a solid or gradiant background color, but nothing about static
images.

Is it possible to add a static image to the background as it is with for
example 3D Studio Max, where it is very simple to do so?

TIA,
Espen

As your case is prety simple, this is a simple solution:
Add a large box behind your animated text. Use an image_map as the texture. 
Translate the image by -0.5 to have it centered, then scale it to fit. Give it a 
finish{ambient 1 diffuse 0} so that it don't interact with the light and don't 
show shadows.
DONE!

Thanx guys!  Below is the code for reference.

, Espen

plane { < 0, 0, -1 >, -15
   texture {
       pigment { image_map { tga "background.tga" } }
       finish { ambient 1 diffuse 0 }
       translate < -0.5, -0.5 > scale < 20, 20 >
   }
}

Before scaling, the image_map cover an area of 1 unit by 1 unit. So, if the 
original image is not square, you need to scale it to the proper aspect ratio.
Your plane is as good as the box I mentioned.
As it is now, the image will be tilled over the plane. If it's incoveniant or 
you don't want the tilling, you need to add the "once" keyword.

And both are as bad if the camera is moving even a bit.
