Citations are a critical component of the academic process. Citations are how we give credit to the sources which influence our work, how we provide support to our ideas, and how we situate our research within the larger intellectual landscape.  

Citations not only assign intellectual value, legitimacy, and authority to scholars and their work, but can also lead other scholars and learners to investigate institutions, authors, and image repositories that could benefit both the creators and the researchers of the material. Even if something is Open, in the Public Domain, and freely available, why not thank the author and anyone who later looks at your work by giving them a roadmap of how you got there? It's as simple as a caption.
