Paypal question

I managed to integrate PayPal payments into a clients Gallery 1.x site thanks to an ingenious hack developed by a wedding photographer for his site which he very kindly shared with me.

Unfortunately, when I went to make an adjustment to the inline photo footer which controlled that mechanism, I managed to cock-up and didn't save the original file first (I know, I know!).

I could spend hours trying to track down that person again (if you're out there and reading this btw, please feel free to e-mail me:

- I've lost your details.

However, probably the easiest thing to do is to upgrade to Gallery 2 because I gather that has an official/semi-official Paypal module, yes?

If that's the case, can you tell me how easy to use and flexible that is? Basically I need the opportunity to choose one of three sizes for each photo ordered and a cart facility built in.

All responses gratefully received - thanks.
