If you simply searched for images without ensuring they were free to use, then you have an issue that you need to correct before you respond admitting to such. You need to use images that won't result in your customers being taken to court over copyright issues.
I'm unfamiliar with terms such as anchors. I'm guessing that the client is asking you for a new URL that doesn't mention someone else's site ? They aren't going to fiddle about trying to achieve that.
Thanks, I'm glad you liked ...
