Use a reverse search in google. Do others the favour, too. In case you find a copy of somebody else's image, report

That's an excellent question. And while Viewbug does take steps to make copyright violation harder, I still wonder if some of my images are out there, floating around and being used without my permission anyway. One thing you might try is to type a search such as "photos of red roses" or whatever subject you've done, and see what pops up. Bing often displays results of hundreds and hundreds, if not thousands, of photo and graphic images of all sorts.

No, I don't know exactly about it...
