A script that uploads photos to Google Photos / Google+ / Picasa Web Albums

• Uploads all directories under a given directory
• Restartable
• Creates the albums as "protected"
• Automatically retries when Google data service errors out.

• Use multiple threads for uploading.
• Deal with 'Error: 17 REJECTED_USER_LIMIT' errors.

• Prerequisites:
  • Python 2.7
  • Google Data APIs http://code.google.com/apis/gdata/

You need to use OAuth2 for authentication. Here is how to set it up:

1. First create a project through the Google Developer Console: at https://console.developers.google.com/
2. Under that project, create a new Client ID of type "Installed Application" under APIs & auth -> Credentials
3. Once the Client ID has been created you should click "Download JSON" and save the file as $HOME/.config/picasawebuploader/client_secrets.json (you can change the location in main.py)

The first time you run the application you will be asked to authorize your application through your web browser. Once you do this you will get a code which you have to copy and paste into the application.

You're done.

Picasa Web Albums appears to have an undocumented upload quota system that limits uploads to a certain number of bytes per month.

Do a web search for REJECTED_USER_LIMIT to see the various discussions about this. From reading the web forums it appears that the upload quota is reset occasionally (possibly monthly). If you start getting REJECTED_USER_LIMIT errors when you run this script you may have to wait a month to upload new pictures.

Some people have reported that paying for yearly web storage will remove the upload quota.
