When a user adds an image into the HTML and then realizes it's in a wrong place and wants to place it elsewhere, then he/she can drag it. The problem is that the drop converts the image into a URL (and an anchor), instead of keeping it to be an image. Note this is drag in the webkit content, not from the outside. I can reproduce this with 2.24.4 and the trunk at r259630 with these steps:

a) run MiniBrowser: ./MiniBrowser --editor-mode
b) type: text
c) click Insert image and add some, say /usr/share/pixmaps/nobody.png
d) type: another text
e) drag the image after the word "another"

Actual result:

   textanotherfile:///usr/share/pixmaps/nobody.png text

where the file:// URI is underlined, a real anchor.

Expected result:

The image is left to be the image, not converted to a URL.
