/// <summary>This method returns the raw contents of the internal file, with the first 12 bytes stripped off. The first 12 bytes are 3 ints. The first, I don't know what it is. The second is the itemID. The third is the size of the image data. None of this is needed to create the image. You can write this raw data out to a JPEG file which can then be read by any standard image viewing software.</summary>
