 **Description:**  
 Combine two images into a single image : a background and one (or several) transparent overlay. (allow for video frames.)  
+Update 0.8 : Also have a option to put image top, bottom or center.
 ❗ Warning : For now, `background` is a static image. (I will allow video there later too.)

+**Description:**  
+Transform greenscreen into transparency.  
+Need clean greenscreen ofc. (Can adjust threshold but very basic node.)
