text: If you make money with those images, or use those images in conjunction with your business, you must get permission from them.  Otherwise, yes they can force you to pay.  And, by the way, you don't get to say how much money those images helped you make and therefore how much you should pay Disney.   They get to say how much those images are worth, get money from you for their worth, and can also get you to pay punitive damages - in other words, extra money just to punish you for doing wrong.  This applies even if you "bought" an image (say, a line art drawing on a clipart CD); read the copyright information on all software, pattern books, etc. before using images.
