TinEye Reverse Image Search is a handy extension for Chrome that allows you to find exact matches of your images in a single click.
Why might you want to do this? Well, as the TinEye Reverse Image Search developer points out, you might want to see if an image is being used somewhere other than its original location or find a version in a higher resolution.
TinEye Reverse Image Search is very easy to use. The extension adds a discreet "T" icon to the bookmarks bar. Clicking on it will open a window that displays all the images that TinEye Reverse Image Search finds on that page.
When you click on the image you want to search for, TinEye Reverse Image Search will open a new tab in the background. Here it will show you what images it finds, including where they are located and the technical details. You can also share the results via Twitter, Facebook or email, save the image, or compare it with others.
TinEye Reverse Image Search also has a few basic configuration options and it works well. Just bear in mind that it will only find exact copies, so it's not useful for finding similar images.
For finding exact copies of your images, TinEye Reverse Image Search is a really useful extension.
