Portrait copyright
When using images in which people are recognisably depicted, portrait copyright :
“The portrait right gives persons the right to object against publication of their portrait." [translation from dutch]
(Source: Wikipedia.nl, 13 april 2011)
This concerns all kinds of images: photos, drawings, paintings, videos etc.
In other words, you must ask the depicted person permission before proceeding to use the image.
