Hey Sherrie,
Over the last 3 years I have had this a few times, in fact I have been given some good advice from these forums on how to deal with it. But the best advice was to send a letter like this to their registered offices:
Dear Sirs
It has come to our attention that you are displaying our copyright material on your website.
(your company name) asserts that the photographs you display are ours, and feature our designs.
You are, by displaying them, attempting to gain a commercial advantage from work that is not your own and infringing our copyright.
We contacted you via email on [insert date] and requested that you remove the material from your site. We have not received the courtesy of a reply to that email. We enclose herewith a copy of that correspondence, and print outs of your website, displaying our copyright material at [insert date].
You are respectfully asked to remove the material from your website within 14 working days. If, after that period of time it has not been removed, we will be consulting our solicitors.
Yours sincerely
Send the letter 'Special Delivery'. Also send a copy of the letter to the web-host and notify them that this infringement is taking place on their server. This has worked for me more than once. Sometimes the owner of the company has no idea where their so-called web designer has unearthed these images from. You will get the registered address of the web-host from Nominet.
A customer of mine who specializes in internet related copyright infringement gave me the above letter as a template. He also told me that people who steal images are by their nature cheapskates and likely to remove the images as soon as they receive your letter.
If after the 14 days you have had no reply you can send a letter to Google inc. they can remove them from search results and will completely finish their business. But this is a last resort that can be legally complicated and possibly costly to everyone.
If you need any help let me know.
Marc
