[SOLVED]How to use custom image upload in CkEditor

Hi all,
I am using CKEditor. I want to use my custom image upload page.
In that page the images will be listed from server and user will be able to select a image and once they click "Insert" that image will be insert in CKeditor.
Iam able to show the Browse Server button by modifying Config.ja file but unable to populate the image url.

Please guide me for doing this.

Thanks
Sourav
