Hi guys,

I have simple image gallery, where images are placed one next to another and the mask is revealing only one of them.  
Now I want to tween position of the images, but when I do that the mask is “traveling” alongside with the images…  
Can somebody post a tip how to detach the mask from the images?

Thanks  
Z
