---------- | ---- | -----------------
`source` | string | Full URL of the image to be displayed
`link` | string | Full URL the preview should be wrapped in
`mimeType` | string | The mime type of the file (not the preview)
`isMimeTypeIcon` | bool | True if `source` points to a mime type icon instead of a real preview

In case the endpoint returns more fields, they should be ignored and are deprecated (only for backwards compatibility usage) or internal.
