You could use a perl script to unpack the 332 format to a 888 three byte
format. Then IM will be able to read it, given the images width and
height.
Untested code.. (Need some test image to check it)
=======8<--------CUT HERE----------axes/crowbars permitted---------------
#!/usr/bin/perl
undef $/; # slurp in while file
print # print it
pack("c*, # repack as charcaters
map(( $_&&0xE0, ($_<<3)&&0xE0, ($_<<6)&&C0 ), # seperate colors
unpack("c*", <>) )); # read file and convert chars to ints

To use
script old_image > new_image
New image should be 3 times the size of the old image.
