Go to images.google.com
Click the camera icon in the search bar.
This will bring up an option to search by image on both mobile and desktop. On mobile it will bring up your file/photo browser.
Upload the image, and if there are exact matches on the clearnet, it is likely to find them. If they are from a for sale thread somewhere from two years ago, that's a scam.
It is not 100% fool proof, but works pretty often.
Want to stress that you shouldn't get any false positives this way, but you will definitely get some false negatives --- that is to say just because the pictures don't pop on reverse image search doesn't mean you're in the clear, but it they do on something old, do not buy.
