I am using nicEdit for user who can add code in editor but when image drag & drop in this box that will redirect the page to perticular url. This error accured in only chrome browser.
nicEdit apparently does not support image drag & drop by default. Check here: http://nicedit.com/demos.php
Here's an alternative that claims to be the first WYSIWYG editor WITH image drag & drop support: https://imperavi.com/redactor/
