This has been made visible by MGNLPER-44, in which a search for an image showed me its 'caption' property, which was wrongly set to the image author.

We should use those properties correctly to make our demos more appealing and more accessible (think Braille readers).

This overhaul is needed for all assets, from tours (CE) to stories (EE).
