Knowing where Twitter's images come from is a good thing.

With the rampant and almost revolutionary spread of fake things across the internet, TweetDeck has announced it's added a feature that lets you verify the source behind an image before you react.

It's easy to use: hover your mouse pointer over the image in the TweetDeck web app and then click the little magnifying glass icon to jump to a Google Search in another window. Google will fetch results related to that image and verify whether it's an original photo or a copied one.

This is what the search icon looks like on top of a photo when you hover over it with your mouse pointer.

This is what the Google Search page looks like after you ask for verification from TweetDeck.

The feature is not available for your smartphone yet, but it should be since you can view images through the Twitter app, too. It's possible that since the ability was originally announced by Twitter's own account feed, perhaps this is an indication that it's someday meant to be a part of the Twitter mobile app. This sort of feature could be greatly beneficial to those who only view Twitter through an app, or even through Twitter Lite.
