TinEye Reverse Image Search

I got interested in knowing what free images I can use in brochures, posters, etc., and I first turned to Google and found webTegrity, which was a big help in how to search for photos and images that can be used without worries about copyright infringement.

After you've located the perfect images, and you just want to be sure, the next step is TinEye Reverse Image Search.

Here's what TinEye says about themselves:

TinEye is a reverse image search engine. You can submit an image to TinEye to find out where it came from, how it is being used, if modified versions of the image exist, or to find higher resolution versions.

TinEye is the first image search engine on the web to use image identification technology rather than keywords, metadata or watermarks. It is free to use for non-commercial searching.

TinEye regularly crawls the web for new images, and we also accept contributions of complete online image collections. To date, TinEye has indexed 11,350,945,081 images from the web to help you find what you're looking for.

There are many people who do want their work shared, and sometimes this comes with certain restrictions. Creative Commons is a resource worth knowing about, if it's your work, and you want to share, but you want certain control over how your work is used.
