I'm running Firefox 18.0.2 on Linux Mint 12.04 and are trying to drag/drop an image into a new Confluence page (we are running 4.3.7).
The image displays in the page, but I can not edit any properties (i.e. size, border, link, effects). If I try and preview, the image disappears, and is gone when I click the Edit or Save.
It works via Insert, Image, browsing to the picture.
Not sure why the drag and drop functionality doesn't work. I've tried with various types of files.
Is this broken for other people?
