Is there a specific order needed to read in the image pixels?  Meaning, you typically need to use the combination functions of:
Redband  = GDALRasterBand(dataset,1)
Blueband = GDALRasterBand(dataset,2)
Greenband= GDALRasterBand(dataset,3)

3. Depending on if Band 1 is Red, then store image data as:
Image[0] = BlueBand
Image[1] = GreenBand
Image[2] = RedBand

This is a very general sense.  I have noticed if I switch the order of GDALRasterband, I am provided with an image that is not displayed correctly (certain colors of off).
