#include <stdio.h>

main()

{

    short int inbuffer[256 * 256];
    char outbuffer[256 * 256];
    int i;

    fread( inbuffer, sizeof( short int ), 256 * 256, stdin );

    for ( i = 0; i < 256 * 256; i++ )
	outbuffer[i] = inbuffer[i] >> 8;

    printf( "P5\n256 256\n255\n" );
    fwrite( outbuffer, sizeof( char ), 256 * 256, stdout );

    exit( 0 );

}

Error checking and enhancements are left as an exercise for the student.

I mean, it ain't that difficult...
