Photoshop: Aligning 2 masks or objects on a specific point
Let's say I have 4 (1 original, 3 changed) polygon images containing the same object with some little changes on the shape (so the resulting bounding box is different as well) and a different position (not rotation, just translation).

So now I have 4 masks, one with the orig image and 3 with slightly different ones (in position and shape - but edges are still untouched). Want I want to do now is define a point on the original mask and "align" the other masks to that point. 

Is that possible? I might need just someone who is thinking out of the box...cheers
