Due to security restrictions on Chrome extensions, photos must be hosted at either Dropbox or Imgur, and due to security restrictions on Inbox, they must be HTTPS links.

To get a Dropbox link, generate a shareable link to the image, then change the bit at the end from ?dl=0 to ?raw=1 - i.e. https://www.dropbox.com/s/abcdefabcdefab/photo.jpg?raw=1
To get an Imgur image, right-click, 'Copy link address', then change the bit at the start from http:// to https:// - i.e. https://i.imgur.com/abcdefg.jpg
