Is there an extension that can be used to integrate Piwigo with http://oypo.nl/Default.asp?taal=en or with Shutterfly printing-service.
I know of the paypal card plugin, but then you still need to do the printing your self, with Oypo all things about printing and collecting the money is done for you.
I second this!!
Shutterfly API http://www.shutterfly.com/documentation/start.sfly
I have also received the suggestion to use Fotomoto.
I haven't done the investigation yet about the best service to start with.
