Copyright Photos host says not responsible

hi

the company i used to manage has developed a beautiful (sarcasm) new website and they have used photos from my wife and i that i must have left on a computer in their company, these underwater photos are clearly marked with a copyright with our copyright.

the response i got from the company is nothing after i asked them to be removed and the host says 'xxxx is not responsible for the Clients content, but I will contact them and inform them about your Email and hope they will remove them.'

Hopefully!? Is this true? What if the company refuses to remove them? The company and host is based in egypt and they have a .com tld can i send them a dmca as the root server for tld .com is in USA?

Any suggestions?

Thanks Ladies and Gentlemen.
