I know Google image search is not a free-for-all to grab any image needed. However, many, many, many clients don't grasp this concept and often request or send images they'd like to use which are clearly a violation of copyrights.
I recently had a client send an image to me which they wanted to use and it, frankly, seemed like too specific an image for the client to be sending. My thought was, based on the clients' business, it was doubtful they paid someone to create the illustration depicted in the image.
So, I did a little reverse Google image searching and found the original, which actually won an award for illustration a few years ago. I immediately knew the image was a violation of copyrights and threw it away. I expressed the violation to the client only to be met with "Do a Google image search for 'XXX XXX XXX' and you'll see everyone is using it. Please use the image."
When designing a piece and a client requests the use of an image they "found", and it is clear it's a violation of copyrights, what should a designer do?
I realize this is a legal question but... Can the designer include a clause in a contract to protect themselves from liability due to these requests? Is this effective?
