NO! ABSOLUTELY NOT!!
You see there is this thing in the United States of America called copyright law. Taking photos or anything else from someone elses website is STEALING! It would be the same as going to their place of business and shoplifting. DO NOT DO IT!
What Should You Do?
You can buy descent licensed stock images from places like istockphoto.com for $10.00/up. We can buy them for you if you need and it will appear on your final invoice.
BE LEGIT: STEALING IS NAUGHTY!
