Images of radio reports, broadcasts, programs, profiles
Images are useful when links to reports or broadcasts are pasted in social media such as facebook, twitter as visuals might more likely attract users to click on it.
If linked to a radio report that picture should be taken, if linked to an broadcast an associated should be taken, fallback would be a picture of the radio program. Example: Picture for "Beatbetrieb 01.02.2010" broadcast with studio guest Frank Turner overwrites generic one of "Beatbetrieb" program.
How to store pictures? Generic approach in a gallery and link to different classes? See https://djangopackages.org/grids/g/gallery/
Images with min. 1,200 px width are required for big preview in social media. What with bigger pictures? Keep original ones?
What about crop to fit a ratio? It depends on the layout of the later front end.
