I don't know about you but I've been collecting a library of reference images that I can turn to for inspiration.

At the moment I just sort them into folders by category. - Interiors - Lighting - Texture - Composition - ect the problem is that I have no way of finding the when/where/who of these images once they've been stored.

I was wondering what people use to keep their reference library organized? Software/Process/Habits ect
