Google really sees all! Just drag and drop a picture from your desktop into Google Images and Google will show you where the original came from as well as all the other sites that reposted the same image. This even works if you have cropped or modified the image!
Google rewards sites that use unique images while copied images hijacked off someone else’s website, can bring your site’s authority down. The lesson here is to buy or create your own images as much as possible and Google will reward you with better rankings and more traffic. I know, its tough but there really aren’t any good shortcuts for producing high quality, unique content. This really sucks because I’m a true image kleptomaniac so do as I say, not as I do! Lastly, this brings up the question of what if any changes this will have on Thumbnail Picture Galleries and Porn SEO.
Drag and drop an image from your desktop directly into the search window of Google images. This works in Chrome, Firefox and IE.
Next you will see the all the places where the image has been posted.
