Capture OK click while inserting images - CK Editor

Hi,

Have been working with CKEditor for a few weeks.
It works like a charm, with the exception of one scenario.

Need to capture the "ok" click event while inserting image.
I plan to parse the local image path, upload in to my file system & change the url to point to it.

Dont want to use a file browser separately.

Thanks & Regards,
Vinayak.
