You can now check out if your images are being used by others

Many of us capture photographs or draw pictures by ourselves to be used in our blogs. But some people use them without our permission. You can now check if your images have been used without your permissions. 

It is a new feature on Google image serach. You can search for an image by uploading it or specifying the URL. More details here: http://www.google.com/insidesearch/searchbyimage.html
