What is worse is when a business just takes the image without the creator’s consent and leaves the creator out of pocket.
Luckily there is a great service called https://www.pixsy.com how it works is that you upload your images to their website and they scan the internet to see if your images have been used without your permission. If they have you can issue a takedown notice to the infringing party and seek payment for the use or just put a stop to the illegal use.
Thank you!
