You’re being a good Net Citizen, participating in your community by weighing in on the posts of your favorite bloggers — but next to other people’s posts they have a picture, where your comments just have an outline. How do the other commenters get their pictures on other people’s blogs?
What they have that you don’t is a gravatar — an avatar linked to their email address that will show up when called for. The good news is that you can get a gravatar too, for free!
The site you need to go to is en.gravatar.com. There’s a great explanation of gravatars on that page, and they’ll walk you through the signup process. (All they need is your email, and you can add other email addresses — even have a different picture for each address!) When you put some effort into “personal brand recognition,” and you use the same avatar wherever you can as a recognition tool, having that gravatar available will be a big help.
If you have a WordPress blog (or at least a WPD blog — I have no idea whether this is a plugin thing or not), you’ll want to turn on gravatars so that everyone will have their picture show there, too. If you log in to www.yoursite.com/wp-admin, and go to Settings->Discussion, you’ll find the “Show Avatars” radio button near the bottom of the page. Click it, and Save Changes. Your time lag when a comment posts might be a tad longer, as the software goes and grabs the image, but I think having the images next to the comments is worth it. Have fun!
