In CDX if you set the RGB to 0,0,0(Black) ,it will display alpha color(transparent) while the picture was showing. I knew that tga type can do this in irrlicht but how about other types like GIFF , BMP, PNG ?

Hmm, I don't see where this library comes in here. So if you have a texture which has no alpha value you can lock the image and directly access the bitmap that way. Not check the format (16bit or 32bit) and set the alpha bits accordingly.
