hi there

could please somebody tell me what i got to do when i want to take a simple background image (a jpg or bmp etc) so that im rendering my character(s) in front of a pic of notre dame or stuff?
Must sound very strange but when i see my ready scene with the model in the front and i add a background pic, i can see it but when i start rendering its not there anymore...

Can you help me?
Thank you sooo much

Stef
