an image you must be able to open the image file. If you insert the CD into your computer's drive and open it you'll see a list of the image files - what happens when you click on one of them?
Normally, image files will be 'associated' with a particular application such as Photoshop for instance, and will automatically open in that. Otherwise they might open in the Windows default image viewer, which is Paint. You can print from Paint, or from any other image viewing/editing software.
