gotta be honest: I am not sure. I say that because background image is not really a good way to go, IMO. If you use image, you have more control - which regardless of your current situation in this sort of thing is going to be better.
i.e. use image on canvas and position as you like
True, i agree that image have more control but I wanted the image to be place in many different states so If I use image I will have to put the same image many times on different states instead of juz 1 go..But I guess now I really got no choice but to put image instead of backgroundImage
