When selling images through stock libraries such as Adobe Stock, Alamy or Getty Images, I often wonder where the image sold ends up. A lot of these images will appear on various websites and using Google can sometimes be found.
To search your image, go to Google and search images, In the search box you can drop your original image, and Google will go off and try to find matches of the image, often revealing the website they have been used on.
My image of the Happeny Pier in Harwich has sold a few times, and carrying out the search as above revealed the image being using on both the Scenic Rail Britain website and also Hotels.com.
