Zoom an image with the mousewheel in AS3

Hello,

I have an image and I want to zoom in and out. I can easily zoom in and out by using the tweener class but I dont want the image to stay in (0,0) and only expand its width and height. How can I make the image depend on where I have the mouse and center the zoom around that or if the mouse is not on the image it should center the zoom to the stage.

The attach code is what I use right now, but it doesnt really work well because I tried to experiment with moving the x and y coordinates with the scale calculations. Though in my head this should still work, have totally no idea why its not.

Well I will appreciate your help, thanks.
