Extremely long URLs -- don't know if this is a bug with the extension or gravatar itself:'

h ttp://www.gravatar.com/avatar/xxxxxxxxxxxxxxxx.jpg?r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60&r=g&s=60

I was able to fix this by changing the line:

            $output[$cur_user['id']] = 'http://www.gravatar.com/avatar/'.md5(strtolower($cur_user['email'])).'.jpg?'.implode("&", $get_vars);

        }

to:

            $output[$cur_user['id']] = 'http://www.gravatar.com/avatar/'.md5(strtolower($cur_user['email'])).'.jpg?'.implode("&", $get_vars);
            
            unset($get_vars);

        }

• don't change file in cache, if you change email

• Not used gravatar if topic starter is guest

fix it please

http://www.itsallpolitics.com/user3.html (show correctly)
http://www.itsallpolitics.com/topic1-test-post.html ( does not show the gravatar for 'chovy' )

After installing this extension the other week I have noticed that the avatars still don't seem to cache correctly.

Sometimes they will just randomly disappear and not return.

This is my forum where  the avatars don't seem to show up even though the extension is turned on.

Changing the rating from say G to PG also causes this issue.

Could explain me what differences between GPL v2 and v3 are

Well, not really indeed. All I'm sure of is that:
- most GPL projects say they are licensed under GPL "either version X of the License, or (at your option) any later version."
- GPL version 3 adds anti-tivoization measures, as explained much better than I could myself there: http://www.gnu.org/licenses/rms-why-gplv3.html

Again, better than I could explain myself: http://www.gnu.org/licenses/gpl-howto.html
You can also see how they implemented it in PunBB: http://punbb.informer.com/svn/punbb/tag … 2/post.php
If you need more details, I would strongly advise you not to ask me , because I'm not really a specialist on license matters. All I do is put most of the stuff I do under the latest GPL (or GFDL) license because it's usually the best for compatibility with materials I use.

Thanks

I'm not sure about the license... does it matter?

Well, I'd like to use your extension as a work base for another extension under GPL v3. I probably won't need to keep much of the code, probably not more than a few lines of it, but if your extension was already GPL it would spare me the trouble of rewriting these pieces or wondering what's the max length of a portion of code that can be copied without it being copyright violation

• when used along with pun_antispam, in the administration panel the Gravatar settings are separated from the avatar settings by the captcha settings

• I believe it's rather some core misbehavior than a problem with your extension, but if "Allow users to upload avatars for display in posts" isn't checked, the Gravatars won't show up. This is a bit annoying if I want to allow Gravatars but prevent ppl from uploading stuff to my server.

Edit: btw, what's the license for your extensions? GPL v2/3?
