Include more than one image on a card but not too many, so that the cards are not too eclectic and the images are easy to see from a distance.

The images may include a country's flag, a person wearing a national costume, a famous landmark, etc. Good presentation will gain better marks. Avoid using pictures which could cause offence.

Illustrations taken from the internet are acceptable, however you need to demonstrate that you have done some work on the design and not copied ready flashcards from the web.
