Difficult to judge without additional information. Is the image file
accessible to the webserver process? Is .tif support compiled into
mapserver? Are its coordinates in the same coordinate system as your
shape files are? The STATUS is set to ON; have you asked for it to be
displayed with "layer=elevation" in your URL? Does the SHAPEPATH in your
mapfile point to the location where the file is located?

I do not have much experience with projections that goes beyond writing
"init=epsg:XXXX" here, but you might want to enclose your parameters in
quotes, like this:

PROJECTION
  "proj=latlon"
  "ellps=clrk66"
END
