Original bug title:
Mobile MediaViewer: In-comprehensive licensing information
Below the picture, something like CC-BY-SA-3.0-2.5-2.0-1.0 or CC-BY-SA-3.0 is written that is hardly useful to anyone. Clicking it takes one to the file description page at which the licensing section is collapsed by default.
Comprehensive license information or some kind of license-logo and a link to the license text.
How to reproduce:
Go to commons.m.wikimedia.org, tap on an image, and make sure it opens in the Mobile MediaViewer. Look on the white band below the image.
