Hi, Related to the usage of Gravatars (http://en.wikipedia.org/wiki/Gravatar) for http://contributors.pharo.org here is some code you can use to check whether your Gravatar image really works: ZnClient new beOneShot; url: 'http://www.gravatar.com/avatar'; addPathSegment: (ZnDigestAuthenticator md5Hash: 'sven@stfx.eu'); queryAt: #s put: '128'; queryAt: #d put: '404'; get; isSuccess. ZnClient new beOneShot; url: 'http://www.gravatar.com/avatar'; addPathSegment: (ZnDigestAuthenticator md5Hash: 'nobody.at.all@gmail.com'); queryAt: #s put: '128'; queryAt: #d put: '404'; get; isSuccess. (ZnClient new enforceHttpSuccess: true; beOneShot; url: 'http://www.gravatar.com/avatar'; addPathSegment: (ZnDigestAuthenticator md5Hash: 'tudor@tudorgirba.com'); queryAt: #s put: '128'; queryAt: #d put: '404'; contentReader: [ :entity | ImageMorph fromStream: entity readStream ]; get) openInWindow. And now you know how simple Gravatars really are, provided you use a proper programming language to access them. Enjoy! Sven
