PICTURE in POI : let display a bigger picture for specific POI (outside the map)

[JLZIMMERMANN]

IDEA :
In some maps several contextual informations are needed, this is why we may add some picture outside the map to let understand who can be involved (or any other kind of explanation).

SOLUTION :
When a POI is used with such choice an option would be welcome to let add like in the left panel

but this option is in the POI : bigget text ( #1884 ) and bigger image

This needs custom icons (#125) and changing icon size (#859)

Here's some feedback from a user:
‘For example our bus icons are too small in the marker or we can't find the right marker to display them. the default marker shape is the one that shows our icon but we don't think it's great and the bus icon is too small.’
