There are two useful tools available to find your artwork. If your work has wide appeal this could be very helpful in helping you retain your copyright.
The first tool is Google Images. This is a great service that allows you to use online images as well as images on your computer. There is no program or application for mobile devices yet.
Here are a couple YouTube videos to help you
1. Google Image Search: I believe that none can beat the power of Google Image Search as it returned the most amount of results for the same image as compared to other websites. Most searches use Google to get results.To upload an image, click on the camera icon in the search bar and in the new window, you will be asked to upload an image from your computer or paste an image link directly. Alternatively, you can also drag and drop an image from your computer to the Google Image logo.https://www.google.com/imghp?hl=en&tab=wi&ei=2D77VfmSMcz0-AGcyZOIBA&ved=0CBYQqi4oAQ
2. TinEye Reverse Image Search
TinEye also performs almost as accurate image search as Google Image with fewer results. This might be because Google Image has more images in its database than TinEye’s 2 billion images. TinEye has something that Google Image does not have – an API. Companies like Ebay and Istockphoto has turned to TinEye to integrate its technology in their app.
3. Firefox Copyright Infringement Finder
Foxfire has a similar add-on Extension to Google: Firefox Copyright Infringement Finder. It is similar to Google Image except you can only use an image which is already available online.
I prefer this to google, it is easy . Right click on object. Open Image Finder- presto!!
