Have Your Own Personal Copy

I'm a member of subscription sites that allow me to create links to images on their sites that requires me to have a subscription to access.

I don't link to the images that are behind the "pay wall." I download images of records that I need to my own media so that I always a copy of the image for personal use.

That way, if something ever happens or I don't have access to the site any longer--I still have digital copies of the images I used.
