La première cause et de loin l’emploi de filtres ‘courrier indésirable’ (spam). Et particulièrement les systèmes qui demandent que l’expéditeur d’un e-mail vérifie manuellement le message. La seconde cause la plus habituellement est que l’adresse e-mail n’existe pas — voilà pourquoi il faut toujours vérifier la soigneusement la saisie de son adresse ! Enfin, il semble que certains fournisseurs de service (tel MSN ou Hotmail) distribuent mieux nos courriers si vous rajoutez ‘support@gravatar.com’ à votre liste de contacts.

We cache your gravatars for periods of time, which means that your new gravatar will take effect after the old one expires from the cache. The reason we do this is to be able to serve your (and indeed everybody’s) gravatar images much more quickly and reliably.

Many sites only support displaying avatars with a rating of G. If your avatar is rated as too explicit (you get to set the rating yourself) it will not be shown on sites that do not support that particular rating. The check tool (http://fr.gravatar.com/support/check) will show you what your gravatar might look like for all ratings. If you wish to change your images rating, simply hover your mouse over the image in the list at the bottom of your manage page, and you will see the rating appear in black. Click on that rating, and choose a new one from the next page. As always give it a bit of time for the new rating to take effect!

The most common reason for this is the rating of the image you are using for your gravatar (see “My gravatar doesn't show up for a particular rating (or site!),” above. After that, the usual reason for this is a common error in making image links on the originating site. (Click here: http://fr.gravatar.com/support/check to double check your gravatar.) If your image comes up correctly, then you may want to direct the site in question to the “I'm trying to implement gravatar for my site, and some gravatars aren't displaying!” FAQ entry below.

This is a pretty concise guide on clearing your cache no matter what browser you use: http://kb.iu.edu/data/ahic.html.

Basically your computer (in an attempt to make things faster for you) keeps copies of things (your avatar image, for example) on your computer, and the next time you request one of those things instead of getting it from the internet it gets that local saved copy. in this case you don’t want the saved copy, you want the new one from the internet. Thats what clearing your cache does... it deletes all the local copies of things that your browser keeps around.

Yes, simply hover your mouse over them in the list at the bottom of your manage page, and click the red “X”.

I’m sorry, we currently don’t delete accounts. If you remove all the images from your account, however, this simulates your account being deleted as far as the outside world is concerned

La plupart du temps, le problème se situe avec l’adresse e-mail. Gravatar utilise exclusivement des adresses en bas de casse (minuscules) pour servir les images, mais une fonction de hâchage (md5 hash) de TITI@TOTO.COM n’est pas pareil que titi@toto.com. Avec PHP, essayez md5(strtolower($email)); (à adapter pour d’autres langages). L’outil de vérification des Gravatars peut être utile dans ce cas.

MD5 is plenty good for obfuscating the email address of users across the wire. if you’re thinking of rainbow tables, those are all geared at passwords (which are generally shorter, and less globally different from one another) and not email addresses, furthermore they are geared at generating anything that matches the hash, NOT the original data being hashed. If you are thinking about being able to reproduce a collision, you still don’t necessarily get the actual email address being hashed from the data generated to create the collision. In either case the work required to both construct and operate such a monstrocity would be prohibitively costly. If we left your password laying around in the open as a plain md5 hash someone might be able to find some data (not necessarily your password) which they could use to log in as you... Leaving your email address out as an md5 hash, however, is not going to cause a violent upsurge in the number of fake rolex watch emails that you get. Lets face it there are far more lucrative, easier, ways of getting email address. I hope this helps ease your mind.
