Another Yafaray question - image background

[micheus]

The background for ambient light will work as an environment map - it will be put around the scene. So, if it's too small the image will become poor.

If you want the image to be in the background of your camera view you have the option to use a image plane for that (will need to adjust its material, since it should not be reflective, emissive, ... - it should be neuter); or you can just render your image with a transparent background (render settings) and merge both using a 3rd part software like Gimp.

The background in the ambient light can be enabled to enlight the scene. Check these samples:
