better to answer to list ... so everybody enjoy solutions
I suspect it's more mapserver related than cw3.
with the help of shp2img you can get directly what mapserver return
( you have to simulate the checked layers etc ) It could be hard to make ecw & mapserver properly linked together
depending on what OS you are using.
Also if ecw take less space on disk, each time you need them mapserver has to uncompress them in ram.
So a judicious calculation between the time loss and/or place should be done.
If you try to import your ecw files inside a soft like udig, qgis did you get also the black background ?
I didn't really know well all ecw problematic, so perhaps someone else can drive you to the right way.
