How do I know this? Because I created that, in 2009, and archive.org can show that (not to mention the vectorial sources I have). He just got the image somewhere and inserted it in his design, selling to his customers as if created by him.
Worse, that image includes a stock photo I acquired from iStockphoto / Getty Images with personal rights. All his clients are infringing their copyright and may get huge bills, sometimes of thousands of dollars. It has happened, many times.
Be careful, never use any template if that seller cannot show he has developer rights to all images.
The risk is all yours, you get the fine, Getty Images doesn't care about any excuses.
