Image scaling

Hi everyone,

I’m developing my first game and I have a great issue; to define both dimensions and x,y coordinates of my images I’m using this two variables :

W=display.viewableContentWidth

H=display.viewableContentHeight

In this way I should adapt every images to the screen size but unfortunately this method doesn’t work so well. Everything works fine in the emulator and in my smartphone, but when I install this app in my brother’s smartphone most of the images come out cut.

How can I solve this problem?

Thanks a lot for your answers =)
