/***********************************************************************
	Following fuction load .dt file
		sName,		the file name
		pWidth,		return the width of the image
		pHeight,	return the height of the image
	return value:
		return a memory block contains the binary image data, with 
			color(RGB,one byte each) of each pixel from left to right, 
			bottom to top.
		For example, if the image is a 10*10 image, then the return 
			value pRes points to a memory block of size 10*10*3, and 
			pRes[0],pRes[1],pRes[2] are the R,G,B color of the first 
			pixel of the image, valued from 0 to 255. 
		
		If failed, return 0 

	NOTE: please add following include codes first
		#include <sys/stat.h>
