I placed a png image on the screen. If I want white to be the transparent colour, is it possible to do it in Irrlicht or I have to use gif with a transparent colour set? So the output is something like this, http://www.hostpic.biz/uploads/1a6d7f2c35.jpg

you can use the makeColorKeyTexture to convert to a texture with alpha channel, but you can also do it with your gfx tool. Then you have to enable the alpha flag when drawing the image to the screen (check the API, there's a flag for alpha transparency).
