I have 2 photos, and i want to animate the first photo, so that when i move my mouse left to right the first pictures moves and the other one reveals. I have attached an example of what i am trying to achieve. So i want to move my mouse over the picture and uveal the photo under it. I hope you understand.  
Thanks

</div>

onClipEvent(enterFrame){  
if(this.\_x\<\_root.\_xmouse-100)this.\_x+=5;  
if(this.\_x\>300)this.\_x=this.\_x;  
}

u can use this code the first one ensures that if the movie clips pos is less that mouse it will increment itself and follow the mouse again if u move the mouse it will be incremented but it cant go beyond the stage which is ensured by the second line (300 is your movie width)

Hope this helps…

I cant really post the fla because it is larger than 72kb. Could you just draw 2 squares instead of the photos to show. The principle is the same.  
Thanks
