"Fireflies?" white dot mystery

Hi im texturing a character with a Gimp 3 layer image, if i save the image in Gimp in any other mode then "Color" i get white dots when i render the mesh. Saving in color mode would be fine but then all the parts that are supposed to be black or white stay gray when rendered. Im relatively sure its not a lamp issue.
I`m using 2.49
Assistance would be greatly appreciated. Thanks!
