We've tried to make it as easy as possible by hosting the banner files on WWF's web server - so in most cases all you'll need to do is follow the directions above.
If you need to host the image(s) on your server for security or performance reasons, you can download the images by right clicking (Ctrl-click on Mac) the images above and choosing "Save picture as..." (or "Save image as..." or similar, depending on your browser) from the menu.
After you have uploaded the image(s) to your server, you will need to follow the directions above to add them to your web page. Remember to update the reference to the image URLs in the HTML to reflect your hosting setup.
