Do I understand it correctly (english is not my language) that DAZ don't get the ownership of the image? I don't know. This is a standard contract agreement used by a number of online sites, but the agreement is written in a way to grant the greatest latitude to the organization using the agreement. It's not clear what rights the artist retains if the agreement grants the contest agencies the right to sell the work without compensation. I guess we'll have to wait for somebody with more of a legal background to provide a reading as to what rights are retained by the artist with this type of arrangement. These kinds of contracts probably arose from overly zealous artists that kept constantly suing the companies that were trying to promote them. Now, the agreements are so broadly written in the favor of the owner of the agreement that they can and probably have been frequently abused. For example, I see nothing in this agreement that would prevent the contest owners from going to a bulk clipart company and selling every image put in the contest as royalty-free clipart.
