Within the bounds of the AP site rules ( #30 )regarding the offering of legal advice I would suggest that you need to take this issue to a qualified professional leagle eagle to get a clear determination of what you can or cannot do with any images.

If you have already signed this contract then you will be "stuck" with the terms unless you negotiate an after the event clause or if you haven't signed anything yet I would suggest that you have the aforementioned legal person negotiate with the contract supplier to include a clause whereby you can display your work.
