Your extension doksoft_ckeditor_instant_preview works fine in Firefox, but is not working for drag and drop on Chrome.
Even your own demo here: http://doksoft.com/soft/ckeditor-easy-image-preview-upload/demo.html does not work with Chrome. Chrome simply opens the image that you drop.
Can you please help? Is this issue going to be fixed?
