Re: [OSCOM] drag-n-drop solutions for ajax

I wrote a Firefox extension once to do this.   You could drag and  
drop from the OS (I tried on Mac and Windows) and it would be sent  
with an async HTTP PUT to the server.

I gave up before doing the next part...integrating it into a page  
editor, so that:

a. You can do several images at once.

b. The images have some kind of relation to the page saved in the  
metadata.

c. The images inherit some metadata settings from the page.

Doing this for IE would require someone that knows how to make a  
signed control, and people willing to distribute that control. :^)

The alternative is as Martin describes, a standalone application that  
doesn't live under the web browser security rules.
