Using Parallel.For may give you a significant performance increase.

img = new Color32[byteArray.Length / nChannels]; //nChannels being 4
Parallel.For(0, img.Length, i =>
{
    img[i].r = byteArray[i*nChannels];
    img[i].g = byteArray[i*nChannels+1];
    img[i].b = byteArray[i*nChannels+2];
    img[i].a = byteArray[i*nChannels+3];
});
