Add Gravatar's Identicon, MonsterID, and Wavatar support

We should support this parameter via the options page.

+1, however I'd like to make it more generic than that.

There should be a textbox to specify the default gravatar parameter. It could either take a URL for a default, or take the 'identicon' string and such.

Perhaps some js selection to fill in that blank properly with the various gravatar built-in options or something.

Note that get_avatar($comment,80,'identicon') in the theme currently works perfectly.

Great minds think alike. I coded up a patch and then saw your comment, Otto, heh.

Anyway, take a look at my patch and let me know what you guys think. :)

Use the current user's e-mail address for fun to display the example avatars

I wish we would go the other way and remove the existing radio buttons. Gravatars are particular to a theme: if a theme designer hasn't made use of the function call, then the radio buttons do nothing. I don't think there is another core admin option quite so dependent on a particular theme's design.

Instead, I've attached a patch for an action hook on that settings page that would allow themes or plugins to add in an indefinite variety of geegaws.

Sorry, but I don't like your patch. Besides making it rather complex for a novice user to add Gravatars to their existing theme (right now, all you have to do is drop in the function), there is Gravatar support in the admin area. Those options need to be there.

I'm not saying my solution is the best out there (although it's the best I could come up with), but it's easy for the end user.

A simple "these options will do nothing if your theme lacks avatar support" message would get the job done IMO.

(In [7879]) Default avatar selector. Props Viper007Bond. see #6802

I hacked the patch a bit to move as much of the logic as I could into get_avatar() and to make everything filterable. I also removed custom avatars for now. Let's bring it back as an upload box.

Sounds good to me and nice trick with preg_replace(). That didn't even occur to me to add forceddefault via that. :D

[ryan]

(In [7886]) Add blank to default avatars. Rename default to Mystery Man. see #6802

[ionfish]

The forcedefault argument isn't being appended to the URL because it's looking for the wrong kind of quotes, so if the user has a Gravatar they won't be able to see the options properly, just their own avatar repeated several times. Patch to fix this is attached.

[Viper007Bond]

ionfish: the <img> tag uses single quotes, so you patch isn't needed.
