Images saved outside of pyplot are not picked up in the gallery

It looks like sphinx-gallery only picks up on an image if it is saved via pyplot. I’m working with a library that uses matplotlib for plotting but does not use pyplot, instead wrapping matplotlib’s object oriented interface.

It would be nice if in addition to intercepting images saved via pyplot there was also a scan for .png files in the directory that executes a given script. That way tools that generate images independent of matplotlib.pyplot will still be able to include images in a gallery.

If this is an agreeable feature to add I’d be happy to take a shot at adding it. Also if my description isn’t clear I can take a shot at making a minimal reproducible example.

This is related to a conversation I had with some of the pycortex people, who were in need of functionality to grab rst image directives in lieu of any interactively plotted viz. E.g., if you wanted to demo something that was inherently interactive but included a sample screenshot in the demo by linking to a PNG file, that image would be shown in the gallery if no other pyplot calls were made.

Closing this as the use case seems to be addressed by our new scraping API, feel free to reopen if I’m mistaken @ngoldbaum
