Are you sure that no image is returned, or is the image just blank (white)?

# for some reason this projection is usually dif from the layer
projection...why?!

It works this way: In the MAP section you decide in which srs you want
to have a look at the maps. In each LAYER sections you tell MapServer in
which srs the data is coded. So you should first find out which srs your
Africa geometry was originally coded in and refereence that in the LAYER
section. Then you can use the same for the MAP section. At last you
retreive the EXTENT of you data. Be careful to put the right values
here, else MapServer will simply "look" at the wrong place to start with
and correctly return a map image - but with nothing to be seen

Cheers, Arnulf.
