How to save an image in UV/Image Editor with grease pencil strokes visible? I made a few grease pencil strokes over an image displayed in UV/Image Editor, is there a way to save an image that includes those strokes (except making a screenshot)? 

Using "Save as Image" saves only the original picture:
The most obvious workaround is to not use Grease Pencil at all and use texture painting instead. The "mode" button should be switched from "View" to "Paint" and then all the paint strokes are saved with "Save as Image" option.
