Most people search with Google using a search term. You can search using an image and Google will try to find something that looks similar. We had this old ceramic figure of unknown origin. While Google search did not match it, the results were interesting.
Simply go to Google Images and click the camera icon and upload the photo.
Google will then do a search for visually similar images. Additional keywords can be added to the search (like porcelain). While the search was unsuccessful, the results are interesting.
