英文....	Pictures or diagrams that clarify or provide an example or visualization. They usually accompany a text; the term is most often used to refer to pictures in books or published journal. For works that explore a subject or are preliminary to a separate, more finalized work, use "studies (visual works)." For paintings in manuscripts, use "illuminations" or "miniatures (paintings)."
荷蘭語....	Afbeeldingen of diagrammen die een verklarende functie hebben of dienen als voorbeeld of visualisatie, en meestal bij een tekst horen. De term wordt het meest gebruikt voor afbeeldingen in boeken of gepubliceerde tijdschriften. Gebruik 'studies (beeldmateriaal)' voor werken die een onderwerp bestuderen of een voorloper zijn op een apart en meer afgerond werk. Gebruik 'miniaturen' of 'verluchtingen' voor schilderingen in manuscripten.
