Browse your Google+/Picasa Web albums and select images or whole albums to insert into your posts/pages. This is an unofficial fork of "Picasa and Google Plus Express".

The fork has been necessary because the authentication for private photo albums of "Picasa and Google Plus Express" has been broken since April 2015 due to changes to the authentication protocol. This is the first release after a major change to the code. Please be so kind and test this version before putting it into production.

This fork supports OAUTH authentication with Google, so you can access private photos and albums again! Currently this only works on a blog-wide mode (Google+ Express access level: blog). I am working on a solution for a per user authentication.

Upgrade notice:

• The plugin requires at least PHP 5.4. Using a version before PHP 5.4 leads to parse errors.
• If you have shortcodes for single images that have been generated using a prior version of "Photo Express for Google" (0.1) or "Picasa and Google Plus Express" (all versions), you'll have to update them to make photoswipe work correctly. Please have a look into the FAQ.
• The prefix for all CSS classes has changed from "pe2" to "peg". Please consider this when upgrading from "Picasa and Google Plus Express".
• The function to store authentication data on a user basis has been removed. The use case for storing it on a per user basis was not clear. If you rely on this function, please post a feature request with your particular use case.

Features:

• Use your Google user to access your photos and albums
• Private album access after granting access via Google auth service
• Select albums / images from GUI listing by album cover and name
• Mobile gallery display support with PhotoSwipe
