Once the entire image has loaded on your screen, right-click (using a PC) or
Option-click (using a Mac) on the image. You will get a list of options.
Depending on which browser you use (Internet Explorer, Firefox, Opera, etc.)
one of those options will say something like: "Save Image As," "Save Picture As,"
or "Save Target As." Choose that.
A dialog will appear asking where you want to save the image. Pick a spot on
your computer (Desktop, My Documents, Home, etc.) and click "Save." Congratulations –
you are now the proud owner of a digital Hubble image. Remember where you put the image,
because you'll have to find it later.
