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 Express 2.

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.

Old changelog of Picasa Express 2

2.2.10

Corrects a bug introduced in 2.2.7 regarding per-post options on thumbnail size setting

2.2.9

Corrects an undefined variable

2.2.8

Corrects a bug with non-proportional image thumbnail sizes
Corrects a bug with images displayed without a caption when captions are enabled, the alignment was not being properly assigned

2.2.7

Added an option to allow single image/video thumbnails to be configured non-proportionally
Added the configuration option for PhotoSwipe to prevent upscaling of images

2.2.6

Added a browser check for Photoswipe to switch to Thickbox if the client is using any version of IE, as the current version of Photoswipe has a bug in all versions of IE.
Standardized the image links in Thickbox-Custom to match those of Photoswipe.

2.2.5

Attempted a fix suggested by Google to show all tag search results correctly.
Corrected the use of the pe2_img_css and style options when displaying an album.

2.2.4

Bugfix for image thumbnail size that was introduced in new posts created after
installing version 2.2.3.

2.2.3

Removed the “Video overlay” option and replaced with Google+’s native “play overlay” for videos
Bugfix: A PHP warning was being generated when a gallery shortcode was wrapped around individual images.
Bugfix: Removed the need for the alignX classes being added to the image when captions are being displayed below the image. This was causing issues with certain themes, and is no longer necessary since the “Video overlay” is built into the thumbnail image.
Bugfix: Changes to the js include method for thickbox used by the dialog to hopefully help resolve some issues certain users are experiencing with media-upload.js

2.2.2

Changed the name of the plugin from “Picasa Express x2” to “Picasa and Google Plus Express”:
- As Google migrates to Google+ from Picasaweb, so is/will this plugin
- Renamed the plugin to hopefully help indicate that and assist with plugin searches
- Plugin URL / SVN name that WordPress uses to update the plugin will remain unchanged so that plugin updates can continue to occur from older versions
Removed the requirement of jquery.mobile for PhotoSwipe:
- PhotoSwipe appears to work properly without jquery.mobile
- jquery.mobile was causing many other issues with themes not designed for it
Removed the reference to the 3rd parameter of “round()”:
- The 3rd parameter of round() was introduced in PHP 5.3, so users of previous versions were getting a warning.
- If PHP version is detected previous to 5.3, it will not call round with the 3rd parameter. This may cause some rounding errors, but will not prevent it from working.

2.2.1

Phototile last row will now properly select a row template so the template
number of images matches the number of images remaining, therefore preventing
the last row of a phototile gallery from being incomplete.

2.2

Phototile support for the image gallery
- Google+ style phototile image gallery option
- Thumbnail sizes are generated dynamically based on phototile layout
- Set the width of the phototile container and the phototile layout sizes to match

Bugfix to move the is_mobile_device function into the class to prevent conflicts caused by the include

2.1

Mobile-friendly gallery option added:
- The link option of PhotoSwipe, an open-source
  mobile-friendly image gallery.
- This is now the default image link option as it provides superior performance in both desktop and mobile clients.
- Added some additional options that display if PhotoSwipe is selected to configure the caption format.
Some additional improvements to the preferences to clean things up and hide options that aren’t necessary based on other option settings.
RSS parsing option has been added to enable parsing the RSS to remove the caption entry for records where Google sends the caption as the image filename when the caption itself is blank.
Some bug-fixes related to caption width and non-width-based thumbnail scaling.

2.0.6

A small release to improve messaging for the Google username check and to
clean up a few additional bugs
- Messaging when checking the username’s validity is now improved
- The FAQ now includes an entry speaking to the old picasaweb “short username” that Google appears to have removed support for
- Some shortcode attributes for gallery shortcodes were previously not being sent if changed in the dialog options. Corrected this and the back-end processing to handle them.
- Some internal code cleanup and addition of some shared code to remove duplicate code.

2.0.5

A small release to add additional style control for captions.
- Added the ability to set classes & styles for the P tag that contains the caption text

- Added the ability to set classes & styles on the caption container if captions are enabled for display
