A script that uploads photos to Picasa Web Albums

• Resizes large images to be less than the free limit (2048 x 2048)
• Uploads all directories under a given directory
• restartable
• Creates the albums as "private" aka "limited"
• Automatically retries when Google data service errors out.

To Do:

• Use multiple threads for uploading.
• Add Progress UI
• Deal with duplicate picture and folder names, both on local and web collections.
  • Currently we just throw an exception when we detect duplicate names.
• Deal with 'Error: 17 REJECTED_USER_LIMIT' errors.

Installation

• Prerequesites:
  • Python 2.7
  • Google Data APIs http://code.google.com/apis/gdata/
    • gdata-2.0.16for Python
  • The BSD "sips" image processing program.
    • This comes pre-installed on OSX.

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.
