The reason you might want to add a low-resolution version into the mix is that it causes the algorithm to “squint.” This results in images that do not quite match on the same level of detail as the high-resolution version. You want to give the algorithm a high-resolution image so it can see and compare images in the finest detail possible. Searching the high-resolution image should be a no-brainer. If you are having difficulty finding your image, you might want to try searching: High-Resolution Image Once we understand this principle, we can manipulate our images to increase our chances of the algorithm finding all places your image appears. But what if you are the creator and you are trying to find where else your work is posted? Tricks of the TradeĪll of these tools are built on algorithms that compare pixels in Image A to pixels in Image B. In order to do that, you need to get permission to use that photo. Of course, just giving credit where credit is due, won’t protect you from a copyright infringement lawsuit. From this limited sample size, it appears that their database is not quite as large as Google (not surprising) and their algorithm isn’t as accurate. In March 2014, Bing released a reverse image search tool, Image Match. Bing only allows you to search by pointing the search to a URL or uploading an image. When we talked about if it was ok (legally speaking) to use a photo on your website, one of the questions on our handy-dandy chart was: “Can you find who took it?” I mentioned that there are services available, Tineye or Google Images, which you can use to perform these kinds of reverse image searches. Today we are going to take we are going to dive in and discuss both of these tools and a couple other tricks that you can use if you are the creator and want to find where else your work is appearing online. However, it took the brilliant minds behind the Internet a little bit longer to figure out effective tools to conduct reverse image searches. You can use Google to search for a unique phrase from the post or turn to sites like Copyscape to quickly find out who wrote that amazing blog post (and who might have ripped them off). Text based reverse searches are pretty darn easy. When you are trying to search backwards to find the source, these searches are called “reverse searches.” So you don’t get a nasty letter, you need to know who created that blog post or image so you can ask permission and give credit where credit is due.
