How do I save images/screenshots in a numbered series?

I'm working on a project that would be even better if I could somehow export a series of screenshots automatically.

The project generates random abstract art and I would like to have it generate an image, save it to a file and then repeat maybe 10 times or so. I already have it generating a new scene on click, but I'm not too sure how to save that as an image from the app and definitely not sure how to trigger it more than once automatically.

Any ideas?

Bump...

I know there's a way I just cant remember the way to do it. It might have been from an addon but I can't seem to find that either.
