Brand new interactions and interfaces. 
Easy to use and quick to get started. 
To clarify:
In GerryChen's post, the suffix of the image URL is just below the bottom of the screenshot of the Comment dialogue box.
In this example, the suffix is in the form
/editor/20151020/5625fc993a14c.pngSo in the Image URL box in the Properties panel in the Editor screen, you first enter:
then you append:
to create the complete URL as GerryChen showed above:
Note that you do not appear to have to click Add Comment for this to work.
then Edit the project information:
page, upload or drag and drop an image into the Attachments area:
When the upload is complete,
Save the attachment:
the browser automaticallys goes back to the Project page:
