Paypal and shipping charges

[gottria]

I have a paypal text file that I incorporate into my galleries and so far it's been working well. But how do I handle the shipping chargers? If I change the shipping value to $2.50 then it charges $2.50 for every photo that is added to the cart, I just need a one time charger of $2.50 for the whole order. I can post my txt file and info here as this is where I got it anyway.
