Click on EDIT post. Copy Picture and then "Control + V". That would work for posts already published without pictures. For new Posts, the Editor will give you option to load picture either from your disk or external url.

Start a new post, upload the picture you want to use and take the link from there and paste in the avatar tab. Hope this helps you.
