After years using EasyEda and a missing feature was not implemmented yet. Inserting an image into PCB design window would definetaly help to Clone pcb´s. 

The actual insert/place image does not help in nothing, as the image is intended to be printed on the  pcb, which is not the case for us who want to copy/clone a pcb. We only need a image, (photo/scanned) , to be displayed on the pcb design window in order to help to copy it.
