The rendering output, by default, is found in ac3dpovfile.bmp, in the AC3D directory. BMP's can easily be converted to JPG by any number of programs. I'm not aware of a switch that causes POVRay to output JPG directly, but there may be one.

Changing the rendered background color is really quite easily done with a sky sphere. Edit the ac3dpovfile.pov file, go to the end and add:

sky_sphere {
pigment { color rgb<1 1 1> }
}

I believe that should give you a white background. Change the <1 1 1> to whatever RGB values you like, using 0 for 'off', 1 for 'on' and decimal values in between for partial values.

I do not know how to change background color without a sky sphere, but I expect POVRay's scene description language help-file would tell you how if there is another way.

Good luck,
