How to display license information for figures?
Currently, license information for figures is displayed in rotated form next to figures, which might create problems with reveal.js plugins, see issue #35 (closed).
Maybe more importantly, license information might be rather long, in particular for CC BY licenses with long lists of contributors and changes.
Maybe license information should be collected on a separate slide, similarly to or even in the same way as bibliographical information? Then, just a hyperlinked citation might be shown with the figure.
Any ideas or suggestions?
