Do you have this addon for v.18?

Hey Narasimha, 

Not sure about the POS part, but this can maybe be "opened" for POS users.  

We struggled quite a bit with image management in odoo, so we developed an easy drag-and-drop interface to upload, remove, swith, re-order images on products.  It's a multi-product view so you can do many products at once.

Kind regards,
