NextGen Gallery API

Hello,

I need to write a script that will automatically create posts from a data file. But in each post, I need to also include a NextGen Gallery [ngg]. So I first need to automatically create the ngg galleries and keep their ids prior creating posts with the right id for each one.

So how can I automatically create a ngg gallery? I have not found any API documentation for creating gallery and upload images in php code.

Many thanks in advance.
