it is too complex ，when you can copy a picture and want to paste into the manuscripts
paste a copy picture
@Elio you can simply simply copy and paste a picture in place when you have a location selected in the editor where you'd like to place the figure in. The one caveat I am aware of is that you cannot currently use copy & paste to replace an existing image, for that you need to click on the image and drag the picture in, or choose it from the File dialog.
If this is not working for you, could you tell us which application you are pasting from and what format the image is?
