I think that both of your pictures are relevant to the topic at hand. However, you can try to use some more specific pictures, maybe with notable people from the United Nations or UNESCO. Also the captions for the pictures are very short, this is probably because there is not specific information to add, as it looks like it is just stock images of people in a work setting.
