I cannot see your pictures, might be a problem from my side..
As I remember I was using very few colors (not more than the 16 very standard one (4 bit)) and then recolored it with MLCAD. I'm not with my computer now so I cannot test but give a try with less colors to see if it fix it. I remember doing the pictures with MS Paint, maybe the software does matter also.
