cannot drag and drop images into kompozer

[bqz69]

I have found out, that it is possible to drag and drop an image direct into
kompozer from dolphin, nautilus and konqueror file manager.

I have also found out, that it is possible to drag a link from firefox
webbrowser direct into kompozer.

This makes it very easy and quick to make a webpage.

It works in 8.04 in both kde and gnome

I would like to know what is needed to make it work in newer ubuntu 
distributions?

My intention is to have kompozer, dolphin and firefox open in the same desktop
window, and inserting images and links direct by drag and drop.
