Windows Users: In Microsoft Internet Explorer, click the image link (select either "800x600" or "1024x768"). When the image comes up to the size you've chosen, with the right mouse button, select "Set as Wallpaper" to save the poster as your desktop background image, or "Save Image As..." to save the poster onto your hard drive.
In some instances you will need to click on the image size that your computer screen is set to (800x600 or 1024x768). This will open the image. Then right click on your mouse and choose "Set as Background." Once this is done, you may also need to right click your mouse again and choose "Properties." Make sure the Display drop down menu (bottom right corner) is set to "center." Then click "apply" and "ok".
Macintosh Users:

picture file on your hard drive. Click Set Desktop.
