You may have noticed that for some people a picture is displayed in the comments and for some there is a blank one. If you want to display your image or avatar in the comments whenever you leave a comment, you need to have a gravatar.
Gravatar means globally recognized avatars and sites like ours use their data to display images. You just have to use the same email ID and name which you used to sign up in Gravatar.
If you do not have a Gravatar or don’t have one, a random generated smiley/image will be displayed. You can use this post for testing your comments. All comments will be approved as long as they are normal & clean.
