File manager

Hello,

I would like to use the Jahia File Manager to upload an image in WebDAV
Simply to say, I am integrating an FCKeditor HTML editor into Jahia and 
would like to place a link/button like 'Upload Image' that should call the 
File Manager popup.
It should be the same view, as I get in Add/Update Container Engine in 
case of a Jahia field of type 'File'.

Is there a way, how I can call the File Manager directly, without having 
any Jahia field and get back the URL/name of the uploaded file?

Thanks in advance!

Sergiy Shyrkov.
