how to extract filebrowser...

Hi, 1st to say FCKeditor is great piece of software!

now, i would like to use fck's filebrowser to select image (file) from server in my form. So idea is that user rather than uploading image everytime, can first check (browse for one on server), and then if image is not found upload via filebrowser.

did anyone do something like that? Basicaly, i would like to have input field in my form and button which clicked would launch filebrowser which would then return file url to my form's input field.

Thanks in advance
