If you have a printer then just print them off. All picture viewing software should have a print option.You can even right-click directly on an icon in your 'My Pictures' folder and select print.
An alternative is to get hold of an empty memory card (like you use in a digital camera) and a card-reader. Drag as many JPG images as you want onto the card and then take it to a photo shop to get them printed (Jessop's, Boots, etc).
You can also get your digital images printed by ordering online and uploading the pictures you want printed.
