I am not quite sure to which photo you refer, I need the name of the thread and the date it was posted and the reply number. Though I can tell you that if it's an old photo I will not be able to give permission for you to use it. Simply because I do not have authority to do so. All the photos I post come from sites that have not posted claims of copyright or from sites that give permission for use in non commercial circumstances.
If you decide to use it then it will be by your own risk alone, I would advise that you add this qualifying statement " That you have posted the photo in the belief that there is no copyright issue and upon proof of copyright being shown you will remove any offending image and you are sorry for any offence caused".
