Here is what I am doing:

I Added wordpress media upload with iframe popup when a button or link clicked. And with click of insert into post the image url placed on a textbox.

send_to_editor() function handles image insertion to editor

window.send_to_editor = function(html) {
     var imgurl = jQuery('img',html).attr('src');
     current_item.siblings('.upload_image').val(imgurl);
     current_item.parent().prepend('<div><img width="300" src="'+imgurl+'" alt="banner image" /></div>');
     tb_remove();
    }

So, you see the default send_to_editor is edited and changed. Now when i try to upload the image from wordpress editor image uploaded and click insert image to post. It doesn't work.

Question: How do i multiple instance of send_to_editor() or parhaps creating and hook new js function to each instant of image uploader so they don't conflict?

Solution:

var original_send_to_editor = window.send_to_editor;

window.send_to_editor = function(html) {
     var imgurl = jQuery('img',html).attr('src');
     current_item.siblings('.upload_image').val(imgurl);
     //current_item.siblings('#logo').remove();
     current_item.siblings('.image-preview').html('<img src="'+imgurl+'" >');    
     tb_remove();
     window.send_to_editor = original_send_to_editor;
}
