Right now, that's an open question as I haven't acquired the real data.

For a test, I just created a ".wld" file that described a jpeg file and 
I'm seeing how it fits in.  From an earlier response, I gather my 
MINSCALE and MAXSCALE settings for the layers will tell mapserver when 
to render the raster?
