Now I’ve installed the Gravatars2 Plugin (Version 2.6.2), from the ZenPax site.

Installations was a little more fiddlier than the other plugins I’ve installed, but I got there in the end:
Place the gravatars2-cache-refresh.php in the root directory of the site
place the gravatars folder in the wp-content folder
place the contents of the plugins folder into the plugins folder.

Activate the plugins and set the options.
I didn’t need to add the CSS Stlye for gravatars to my theme, as it already had something set.
I also didn’t need to add the required code to my comments.php file, as it too was already there.

From this site, I discovered that there is a gravatar signup plugin, which I thought might make it easier for some of my readers to get a gravatar. However, that page had been moved to here. From here, I was able to download and install it (straight into plugins folder) and activate it. Hopefully some more people will get into the gravatar thing.

Ohh, for those of you wondering what a Gravatar is, go visit the site.

I can display any gravatar I’d like in a post by inserting this code:
