PHP: Как получить аватарки из Facebook, google, twitter, tumblr?

May 5, 2015

Очень удобный и простой скрипт под катом.

function get_avatar_from_service(service, userid, size) {
// this return the url that redirects to the according user image/avatar/profile picture
// implemented services: google profiles, facebook, gravatar, twitter, tumblr, default fallback
// for google use get_avatar_from_service('google', profile-name or user-id , size-in-px )
// for facebook use get_avatar_from_service('facebook', vanity url or user-id , size-in-px or size-as-word )
// for gravatar use get_avatar_from_service('gravatar', md5 hash email@adress, size-in-px )
// for twitter use get_avatar_from_service('twitter', username, size-in-px or size-as-word )
// for tumblr use get_avatar_from_service('tumblr', blog-url, size-in-px )
// everything else will go to the fallback
// google and gravatar scale the avatar to any site, others will guided to the next best version
var url = '';

switch (service) {

case "google":
// see http://googlesystem.blogspot.com/2011/03/unedited-google-profile-pictures.html (couldn't find a better link)
// available sizes: all, google rescales for you

break;

//TODO do something smarter with the ranges
// available sizes: 16, 24, 30, 40, 48, 64, 96, 128, 512
var sizeparam = '';
