This plugin hasn’t been tested with the latest 3 major releases of WordPress. It may no longer be maintained or supported and may have compatibility issues when used with more recent versions of WordPress.

  • Plugin settings
  • An example of the phototile gallery layout


  1. Upload picasa-express folder to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Use Settings link under ‘Settings’ -> ‘Picasa Express x2’ and set user name and other parameters. If you need private albums access (required for tag searches) use the link under the username field to request access from Google.
  4. In the edit post/page screen use the picasa icon next to ‘Add Media’ for image/album selection dialog
  5. Select an album or image to insert into your post/page:
    • To insert a whole album, click the “Album” button so it toggles to “Shortcode”, then click on the album you wish to insert
    • To insert an image, click on the album the image is in, then select one or more images. When done selecting images, click “Insert” to insert all of the selected images


Tag searches in albums returns inconsistent results

Google+ / Picasaweb tag searching currently contains a bug that causes images
to slowly start dropping out of tag search results, causing fewer than
expected images to be returned.

I have posted several issues and am following threads like the following:
Google Groups: Picasa Data API

Hopefully Google will discover the cause of the problem soon.

After upgrade, selection dialog displays blank screen

If the upgrade to version 2 causes the selection dialog to no longer return
albums and photos, this is probably caused due to changes in the token
authorization process.

Changes were made to the token authorization process to fix issues on Google’s
side, and these changes have altered the URL used to generate the token. This
can cause Google to think you’re providing an invalid token.

To fix the issue, simply revoke access (through the plugin) and request it again.

After upgrade, images return a shortcode

After upgrading from version 1.x, single images selected in the dialog return
a shortcode ([pe2-image …]) rather than HTML.

This was intentionally done to allow for the plugin to compensate for changes
Google is making as they transition Picasaweb to Google+. If you still wish
to have the dialog return HTML rather than the shortcode, there is an option
in the settings that can be changed to enable returning HTML.

Username validation fails

If when in the options and configuring the username, the “Checking user:” test
returns an error, it could be related to changes Google has been making when
migrating from picasaweb to Google+.

The error message provided should give you a URL you can click, which will
then provide you with Google’s error message. In most cases, the error
appears to be related to older “short username” values that Google no longer

Simply change the username you are using to your Google email address and save
the settings.

If this still doesn’t work, check your hosting provider’s PHP preferences – some hosting companies disable connect functions and WordPress can not request data from other sites.

Error with media-upload.js

When attempting to insert an image into a post and receive the error:

“Error: Cannot insert image(s) due to incorrect or missing /wp-admin/js/media-upload.js”

There are several possible causes for this:

1 – if you attempt to open the selection dialog before the page has

completely loaded, some of the required JavaScript libraries may not be loaded
yet. Refresh the page and wait for it to load completely, then try again.

2 – it is known that the “CKEditor for WP” plugin conflicts with the

media-upload.js file. Disable this plugin and try again.

How can I select several images to insert at a time?

When browsing the album’s images you may click on multiple photos to insert at once. These images will be inserted into the post as using the thumbnail size you have defined in “Single image thumbnail size” in settings.

If you have selected the option to “Relate all of a post’s images” and you are
using a link type of one of the thickbox, lightbox or highslide libraries, all
of the photos within the post will be related for next/prev navigation within
the display window.

How can I select several images for “Gallery” display?

There are two options to filter images in a “Gallery” display:

#1 – Use tags to filter photos in an album so that only photos with a specific
tag are displayed.

This is done by inserting an “Album” shortcode, but in the “Options” prior to inserting populate the “Photo tag options” to select photos with the “Featured” tag, or a customized tag name typed into the text box.

NOTE – filtering by tags requires private album access. This is a
Google+/picasaweb requirement.

#2 – Manually select the photos (and optionally their sort order).

This is done while browsing an album’s photos, click the “Image” button.
After clicking the “Image” button, it will switch to “Gallery” indicating that
any photos selected this time will be inserted into the post in “Gallery”
format using the default blog thumbnail size.

I want private albums browsing

On the settings page press the link under the username field titled “Request proviate albums access”. You will be redirected to Google and asked to grant access. If you press the “Grant access” button on Google, you will be returned to settings page and access will now be granted.

After successfully authorizing the access for the blog, the next time you open
the album / image selection dialog, you will see all of your photos and
albums, including any private ones.

I revoked access to my server on Google’s site, and now the plugin doesn’t work

On revoking access through Google instead of this plugin, Google will not inform your server. If you revoke access on Google’s side, you have to clean the option ‘pe2_token’ in the DB or click the “Revoke access to private albums” link on the settings page.

Caption widths aren’t determined correctly

If you’re using a single-image thumbnail width dimension of “Height” or “Any”, the width is dynamically based on aspect ratio. Thus the value generated for the caption is not terribly accurate, causing strange caption wrapping sometimes.

The best solution here is to change the single-image thumbnail dimension to “Width”, because then the width of the caption can be determined precisely.

Another option would be to try a “Caption container style” setting of “width: auto;”, although this isn’t ideal either because it will scale the container to fit any size of caption text, and the text will never wrap. The recommended solution is using a thumbnail dimension of “Width”.

blatant self promotion

Installing this plugin puts the a link with following link in the footer: "With Google+ plugin by Geoff Janes and Thorsten Hake". This is inappropriate, to put in such self promotion on other people's property in exchange for installing such a limited plugin.

Contributors & Developers

“Picasa and Google Plus Express” is open source software. The following people have contributed to this plugin.




  • Embedded video support (currently doesn’t appear to be allowed by Google)
  • Single image selection enhancement – use mouse click mods: Shift (for lines), Ctrl (for columns) and Ctrl-A for all images
  • Add the button to Visual toolbar of Tiny editor in full screen mode
  • Work with Google to correct tag searching index issues which cause tag searches to return unexpected results.


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


  • Corrects an undefined variable


  • 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


  • 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


  • 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.


  • 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.


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


  • 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 for PhotoSwipe:
    • PhotoSwipe appears to work properly without
    • 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.


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.
