We don't want competitors to be able to download high resolution images from Magento. The front-end URL is:
leatherjacketgear.com/media/catalog/product/cache/1/thumbnail/70x80/9df78eab33525d08d6e5fb8d27136e95/a/r/armani-quilted-leather_2.jpg
But you can remove this part of the URL
/cache/1/thumbnail/70x80/9df78eab33525d08d6e5fb8d27136e95
and find the original image here:
leatherjacketgear.com/media/catalog/product/a/r/armani-quilted-leather_2.jpg
:( The original image is returned.
This is not okay with our customer for whom we've done website designing in Magento. They want to protect their images because some companies with in-house developers steals images.
