Debbie, who is a relatively recent visitor to my blog, but fast becoming a regular (I *think* she’s even in the process of transferring over to our hosting service as I write this) made a suggestion about making a post here about Gravatars - - claiming she just can’t figure out those darned things!!

What is an Avatar??
First, a definition. An avatar, as it relates to this post, is a graphical representation of a person. Usually a small-ish icon that gives a visual identity to a name. You see them in use in bulliten boards, discussion forums, chat rooms.. and the like.

What’s with the G?
Gravatars are global avatars - hence, the G. The service can be found at http://gravatar.com. The basic idea behind Gravatar is to provide a global avatar that follows you around the web wherever you go - - and the avatar appears on sites that are Gravatar enabled (like mine is). So, on blogs that are Gravatar enabled, whenever you comment on that blog using the e-mail address from your Gravatar account, your (G)avatar will appear in the comments - either next to your name, or next to your comment text. Having a Gravatar and using it in such a fashion is just another way to individualize your presence on the web.

A little Gravatar history
Currently, Gravatar is owned by Automattic - the fine folks who brought WordPress.com into existence. Automattic’s acquisition of Gravatar happened in October 2007 - they purchased it from Tom Werner. While Tom owned and operated it - it grew at an amazing rate and became extremely popular! So popular that he started having serious problems handling the scale and scope of the project and, as a result, the service itself suffered from extreme lag time, which eventually lead to grumpy users who began to abandon Gravatar altogether because it took way too long for the service to load - - slowing down Gravatar enabled blogs everywhere. And we all know how much we hate slow load times!

Matt Mullenweg made this statement on the Gravatar blog regarding the purchase:

The best ideas are often the simplest. (At least in hindsight.) The idea of globally-recognized avatar, or Gravatar, struck me from the first time I heard it. Of course I should be able to have my avatar wherever I go! Of course email is a great way to key it! Of course there should be an open API for any platform!

Watching how Gravatar changed and evolved over the years I saw a service with great adoption and potential, but facing some classic problems of scale that successful sites are often lucky to run into. Scaling happens to be something my company, Automattic, is very good at, and as we started chatting with Tom Werner of Gravatar it became obvious there’s a lot of potential for combined forces, and I also saw a lot of parallels to Akismet, a product that does one thing, does it well, and has an open API so any platform can use it.So we worked out an arrangement to transfer the code and service from Tom to Automattic,

Since that move happened - there have been no troubles with Gravatar serving up avatars to millions of happy followers everywhere. At least none that I’ve seen - - your mileage may vary. I was a pre-Automattic Gravatar user, myself and I was one of those grumpy users who abandoned the service because of the excruciatingly loooooooooong time it took for Gravatar to load on my site. Since Automattic took over - I haven’t had an issue…yet.

How do I get a Gravatar??
The solution is as simple as it is easy - - visit http://gravatar.com and register there for an account. Once you’ve done that (and activated your registration via e-mail) - you can login to the Gravatar site and upload your own avatar of your choosing and associate that avatar with your e-mail address.

Once that is done and you’ve confirmed your choice - - anytime you visit a Gravatar enabled blog or website, and you use the e-mail address that you registered with Gravatar… your avatar will appear like magic! As an extra bonus - Gravatar does allow you to create multiple avatars with multiple e-mail addresses.. so, if you use different e-mail addys across the web, you can define an avatar for each one!

How do I enable Gravatars on my WordPress blog??
THIS part is even simpler - but it does require a plugin. There are quite a few Gravatar plugins for WordPress floating around out there - - the one that I’ve chosen to use on this blog is Easy Gravatars written by Dougal Campbell - “This plugin will display gravatars for the people who comment on your posts. You do not need to modify any of your template files — just activate the plugin, and it will add gravatars to your comments template automatically.”

Once you install and activate the plugin - - you can configure the settings for it in your WordPress administration panel under Options/Easy Gravatars. Here’s a screenshot of the options menu for Easy Gravatars:

The options are pretty straight-forward:

1. Size in pixels (maxiumum 80): You set the pixel size for the avatars that display on your blog. Basically - how big or small do you want those avatars to be? Based on the screenshot above, you can see I set mine to 50 pixels.
2. Allowed Rating: Just like in the movies: G, PG, R, X. Not all Gravatars are created equal. Some are nice and cute - - while others can be pretty racey to downright raunchy. You can set the type of Gravatars you want to display on your blog. If you run a family-friendly site, you probably don’t want to display X-rated Gravatars, eh?
3. Default Image URL: This is the default image you want to display when a user does not have a Gravatar. In my screenshot, you can see I have a yellow smiley face. This yellow smiley face appears in the comments of my blog for users who have not signed up for Gravatar. The URL needs to be the direct URL to the image you want to use.
4. Span Style: This allows you to create some inline styling for your Gravatar, which gives you a little bit of control over how it appears on your site. Using this Span Style setting - you can give your Gravatars a border, some padding, place margins or background colors, etc, etc.
5. API Hook: you have two options here “Comment Text” or “Comment Author Link” - - this option tells the plugin where you want it to place the Gravatar on your blog. If you choose “Comment Text” (as I have) - then the Gravatar will be pulled in to the same area as the comment text (like, right next to it, etc). If you choose “Comment Author Link” - then the Gravatar will be called in with the Comment Author Link.

Here’s a comment left on my blog by someone who doesn’t have a Gravatar account (thus, my default avatar image is showing in their comment):

Here is an example of a comment I left on my blog, and since I do have a Gravatar account - my Gravatar appears on my comments:

All very easy, simple and straight-forward. Now you can go grab a Gravatar for yourself and further individualize your presence on the web - - at the same time, you can enable Gravatars on your own WordPress blog, for a more pleasant and personal experience for you and your readers.

Hope you’re having a great weekend!
