You can choose to have the URL rewritten but if the images exist on your server, there's really no need in doing so as image URLs are rewritten to hide the fact that the images are being served from merchant sites and not your own.
So, in order to take advantage of having the images hosted on your server, you should set the following URL Settings fields as such:
That should give you cached, fast loading images with no footprinting or reference to merchants.
Make sure to update your store after you make those changes.
