This article explains how to use a Facebook image search method using the image ID number. It also includes information on how to perform a reverse image search in Google.
How do you find someone on Facebook through a photo?
Facebook assigns a numeric ID to all photos uploaded to the social media channel. By default, images downloaded from Facebook have that numeric ID as part of the file name. If you know this number, you can use it to find the source of the image on Facebook.
Right click on the image you want to search for on Facebook.
Select Open in new tab in Google Chrome.
