TinEye has a web browser plug-in, so you can right click any image on a page and search the database directly. The free plug-in is available for Internet Explorer, Firefox, Chrome, Safari and Opera. To use, pick any online image.

1. For this image, we want to find a higher resolution version. Right-click the image and select “Search Image on TinEye.”

2. TinEye found 121 results, and using the Biggest Image sorter, there is a 800x635px version available*.

TinEye, the reverse image search site can also be used for some detective work.

Let’s use TinEye to check if an image is being used by another website without permission. Here is a beautiful photo by my friend and incredibly talented photographer, Rikk Flohr, from his webpage.

1. To do a quick web search for non-permitted use of this photo, I loaded it into TinEye using the drag and drop feature.

2. TinEye’s search only found 1 result, which is actually Rikk’s Flickr account.

3. Of course, no search engine covers the entire internet. TinEye is constantly crawling webpages and updating the image database. And this image search proves it is possible other instances of an image exists online. The test image was found on Rikk’s Flickr account, but missed it on his actual webpage. I assume TinEye hasn’t yet crawled Rikk’s site or it is possible the site is already protected in which case TinEye can’t get the image information.

TinEye is a reverse image search engine. It can be a great resource for presentation design.

TinEye lets you upload, or link to an online image, and see where it came from, find higher resolution versions, how/where it’s being used and if there are modified versions. It is the first image search engine to use image identification technology rather than keywords, metadata or watermarks. When you upload an image to be searched, TinEye creates a unique digital signature for it, and then compares this signature to every other image in their index to find matches. In our tests, TinEye did not generally find similar images, but exact matches – including those that have been cropped, edited, or resized.

The free service allows 50 searches per day, up to 150 searches a week. There is a paid version of TinEye which allows for more searches.

TinEye is easy to use. Here is our sample image and the goal is to find a high res version.

1. On the TinEye webpage, click “Browse” to upload the image. The sample image is fairly small at 350×520 pixels.

2. TinEye search of its database for this image found 80 matches.

3. The default search result is set to Best Match.

4. Changing the sort by Biggest Image, I find a link to the same image that is 1600×1200 pixels!

Note: Most images found online are protected by copyright. If you would like to use any image found through TinEye for commercial purposes, you should confirm it is available under Creative Commons, or contact the image owner for permission.
