How to make friends sceditor and image upload code?

Question

JavaScript

I decided to use the www.sceditor.com bb code editor in the project.

Before that, I had a button above each textarea that called a script for uploading an image to the site in a separate window - after the upload was completed, the bb code of the image was fasted in the textarea.

Several questions

- How to get the ID of that textarea with sceditor-om where the standard add image button of this editor was clicked. I want to hook the code of appearance of my window for loading a picture to pressing of this button.
- After the image is loaded, should I insert the bb code into the textarea or into the sceditor? Or both here and there?
