/*
Header (6 bytes as 3 words)
word1 (Hi:Lo) = width : horizontal size of the image
word2 (Hi:Lo) = height : vertical size of the image
Word3 = colour_mode : 16dec = 65K colour mode, 16bits/2bytes per pixel (msb, lsb)

The header is then followed by the pixel data
Pixel1�PixelN: Image pixel data and N is the total number of pixels
