I haven't implemented this in PHP, but I have a bash script that uses curl to connect and interact.
You can follow the directions for ClientLogin<http://code.google.com/apis/accounts/docs/AuthForInstalledApps.html#ClientLogin> and use the php cURL methods to build the request for authorization. Then parse the response, pull out the auth token and use that in your request header to the PWA API. -- You received this message because you are subscribed to the Google Groups "Google Picasa Web Albums API" group.
