Evaluating Sources

Check whether an image has been used before on the internet and where by doing a reverse image search. 

• Is that image from a suspicious news source one that was stolen from elsewhere on the web and changed?
• Was the image from a past or different event altogether?

You can even use a reverse image search for a profile photo to see if it might be a fake account.  Note: just because you don't find a match doesn't mean the image isn't on the web.  (No search tool is perfect or definitive.)
