I found this article that I wanted to share.

When it comes to protecting your online photography there are many ways to prevent people from copying or distributing your artwork.
If you are like me you have probably uploaded your precious photography at one time or another to either your own website / blog, or to an online gallery such as PictureSocial, 500px or Flickr. The benefit to showcasing your imagery is obvious, you want visitors to see your work, but you want your work to be secure and represented the way you want and, importantly, where you want.
The first thing I recommend is to visit the mighty Google Images page. Where Google.com is unmatched for searching textual data, Google Images is the king of pixel based searching. Google Images utilizes a special algorithm to find imagery that is exactly your work and imagery that is visually similar. The interesting thing with Google Images is that you can drag and drop your photos directly onto the search bar. Of course, if you want to be boring, you can always just use the camera icon.
TinEye is another reverse image search engine. Very similar to Google Images but it offers many additional services including the ability to register your imagery. 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.
Additionally, you can use it as a tool to locate higher resolution versions of imagery (which seems extremely hypocritical considering the nature of this article – but, I digress). Either way it’s tremendously useful for tracking down your online imagery.
