Joey I am sorry to tell you this but unless the photographer has transfered copyright to you, you have no right to use them on any site.
Even when paying a tog you only pay for his time and a set of prints. This is why you should either use your own camera or find a tog who is willing to assign all copyright over immediately.
1.Who owns the copyright on photographs?
Under law, it is the photographer who will own copyright on any photos he/she has taken, with the following exceptions:
?If the photographer is an employee of the company the photos are taken for, or is an employee of a company instructed to take the photos, the photographer will be acting on behalf of his/her employer, and the company the photographer works for will own the copyright.
?If there is an agreement that assigns copyright to another party.
In all other cases, the photographer will retain the copyright, if the photographer has been paid for his work, the payment will be for the photographer?s time and typically an allocated number of prints. The copyright to the photos will remain with the photographer, and therefore any reproduction without permission would be an infringement of copyright.
