Import External Website Images via Drag and Drop for Magento

I have searched and found nothing thus far other than some JavaScript that will actually provide the image URL from an image from an external website.

There are some Magento extensions available that allow you to drag and drop images into the Magento backend product page from your desktop. However, I am trying to find one that allows you to drag and drop images from my vendor's external website.

Would anyone know of a Magento extension that could do this?
