I've not read any of the content of your site but you should know that using any photos from anyone else without their permission is a violation of copyright law. Any of the photos on your site that are not your own, if you do not have written permission to use them, you should remove them from your site as you could be liable for significant fines (as much as $100,000 per photo).
I've still not read the content of your site but going back to the photos, if he never answered, you don't have permission and you are still legally at fault if for any reason he decides he doesn't want you to use the photo. I know you have photos from adcham.com, at least one user from this site, product photos from somewhere and a map that was taken from somewhere. Each of these are subject to copyright protection and you'd be smart to get rid of any photos you did not explicitly get written permission from the owners to use.
