To all you graphic designers / illustrators out there...

somebody who tells a photographer what to shoot and changes things until they are happy, either that or they sit in the corner looking at facebook on their laptop and occasionally look up and say "yes that will do".

Excellent! Very funny and pretty much on the money MrSmyth.

Crispin G in advertising agencies the people that come up with the ideas for ads, visual/headline if it's print/poster/etc or visual interpretation/script if it's film (telly or more commonly these days online) are generally known as 'creatives' and they'll either be an art director or a copywriter. The art director is pretty much responsible for how something looks and the writer for what it says and what the message is. Art directors and copywriters work together in teams.

The creative director will look after/manage/groom a number of teams within his/her creative department. And eat too much at posh restaurants.
