Since I am unable to attach an image to this logbook, I made a post over the the Linux Demo logbook showing an image that was uploaded with the CKeditor toolbar "Image" button that doesn't link to the full resolution image. 

Incidentially, Dario Milicic's recent commit to the git repository (83a10a5), adds the exact functionality I'm looking for to drag-and-drop attachments with the "dndfiles" CKeditor plugin. I've looked througe the "image2" code myself, but I don't have much experience with javascript, and haven't figure out how to do the equivalent for that plugin. 

Thanks for your time.
