Summary: Add Email variable to gravatarplugins default image url

Initial Comment:
In order to allow the md5 hash of the comment submitters emailaddress to be used in the default image url passed to gravatar, I created an %email% var with gets substituted in the gravatar default url prior to appending to the image url. I also had to url-encode the resulting url in order to allow any request parameters be passed to the default url. The resulting patch is appended.

Ah! Of course. That makes sense. :-)

I just committed your patch to the gravatar plugin!

Thanks a lot for your input,
Garvin

Sure :) The reason I needed the md5 hash in there was to allow MonsterID
(http://www.splitbrain.org/projects/monsterid) to work properly. It
generates a random monsterimage (eg as fallback image for non-existent
gravatars) based on a given seed (e.g. the md5 hash of the submitters
email). Makes it possible to distinguish J.RandomPoster A from
J.RandomPoster B at one glance even if they don't have a gravatar account
(and also looks kind of funny)

The possibility to add the md5 hash of the emailaddy to the fallback-URL
enables you to use whatever fallback-image-generator you can think of, so I
thought it might be of general interest, taking into account stuff like
http://www.docuverse.com/blog/donpark/2007/01/18/visual-security-9-block-ip-identification
as well

Can you explain why the md5 hash of a submitters email is useful in the
'default' URL variable? The submitters email should only be used for the
"real" avatar, not the default avatar?

I mean, shouldn't the reason for a default-avatar be that it shows a
static avatar?

Maybe I'm just not understanding things, so I'd love if you could lighten
me up :)

Best regards,
Garvin
