I updated the alt tags in this script. Currently they say things like "make payments with paypal it's fast, Free and secure. I revised this to read "alt='Add ".$args['name']." to your paypal cart'" on line 24. Then I revised the other button to read "alt='View your cart and place order!'" on line 39. With this simple mod, you can have many dynamically and uniquely identified buttons to add multiple items to cart. I did test it and it works across multiple pages of a site. Contextually appropriate alt tags help blind people such as myself and I think it adds a touch of class to the script.
