Mediakit decides how to present a file from its extension, using two maps of extension to media type. Both are defaults you can replace — see Configuring File Types.

How a File Is Presented

Only images render a thumbnail or open full size. Every file, whatever its type, can be downloaded.

Image Types

Extensions in the default image map (nextedy.files.imagemimes): The same map as the property’s default value, ready to copy when you replace it:

Other Media Types

Extensions in the default other-media map (nextedy.files.othermimes): The same map as the property’s default value:
Recognised is not the same as playable.An extension in this map is identified and given its type icon. That is what the mapping controls. Whether a given format plays or previews inside the browser is a matter for the browser itself, not for Mediakit.

File Details Shown

For every file, the gallery holds the file name, its size, the author who added it, and the date it was last modified. List view displays them; grid view shows the file name only.

Configuring File Types

Replace either map to add or remove a format.
