When you are viewing a web page you can save it (or at least the basic HTML or similar source text) to your local disk with the Menubar Location->Save As... item or Ctrl+S. If the page you are viewing uses frames, then you will also be given the Location->Save Frame As... option.
If the page uses a background image, you can get and save that with the Menubar Location->Save Background Image As... option.
But if what you really want is that glorious picture of the latest Ferrari, then right mouse button clicking on the image will give you a drop-down menu with a Save Image As... option. If you choose Copy Image Location instead then the URL will be copied into the clipboard so you can then paste it anywhere you wish. Be sure to respect the owners copyright, and ask for permission before using any pictures saved this way for anything other than your own viewing pleasure.
Right click on a link (which may be an image) and choose Copy Link Location. This copies the URL to the clipboard so you can then paste it into, say, an e-mail to a friend telling her about this wonderful new site.
Printing a copy of the page you are viewing is easily done with the Menubar Location->Print... or Print Frame option, with Ctrl+P or with the Toolbar Print button.
