How to find the source of an uncredited image
- Install Jarred Bishop’s excellent img-src bookmarklet, or a browser extension (Chrome, Firefox, Safari), or simply enter the image URL into Search by Image.
- The largest or oldest image in the results is usually the first one posted on the web.
Of course, this method is not foolproof, but it works so often that there’s really no excuse not to credit image sources. Don’t break the chain of source information and don’t tolerate chain-breakers. You have the power to make the web a better place.
