Inpute file form

Beste,

Ik heb een werkende contact formulier. Nu wil ik er nog een file input veld bij (deze is al aangemaakt ) maar werkt niet.

Ik weet wel nieuwe velden aan te maken (ook werkend), alleen met type input is het voor mij wat lastiger.

Wat moet ik hierin plaatsen om afbeelingen met een contact form mee te sturen (de velden zijn al aangemaakt).
