Picasa Photos


Google Photos vs. Picasa (#)

With the shift from PicasaWeb to Google Photos, Google has killed the capability to display all photos in a single shot for unauthorized users. You could, earlier, display photos for a user in Picasa use the following syntax:

 [gallery type='picasa' user_id='xyz' kind='photo'] 

However, now the above will work only if you enable back-end authentication by providing a “Refresh Token” in Photonic → Settings → Picasa → Picasa Options → Refresh Token (for Back-end / Server-side Authentication). See this for details.

Displaying All Photos (#)

The following pulls some of my photos. The key parameters here are user_id (set to my user name), kind (set to photo), and max_results (limits it to some instead of all photos):

[gallery type='picasa' user_id='sayontan' kind='photo' layout='random' max_results=30]

Photos from an Album (#)

If you want photos from a specific album you can say:

 [gallery type='picasa' user_id='xyz' album='abc'] 

Here are the photos from one of Kokonad’s albums (authkey protected):

Though the above album is authkey protected, I am authorized to see the photos. So I can display them using my “Refresh Token”, without providing the authkey.

You can add further constraints such as the number of photos and the number of photos per row:

 [gallery type='picasa' user_id='xyz' album='abc' max_resuts='m' columns='n'] 

This is one of Kokonad’s albums with max_results=10 and layout='random':


“Show More” and Paged Results (#)

If a search result has a lot of photos and you want to reduce the count, Photonic offers a couple of approaches:

  1. For Picasa, use the max_results attribute documented above, and add an additional tag, more. This will initially show you the number of photos specified in max_results, and a button to load more images. Upon clicking the button you will see an additional set of photos as limited by max_results. The button will continue to show until you have exhausted the entire set of photos.
  2. Photonic can be used in conjunction with <!-- nextpage --> to display photos in a paged manner. For this you can structure your page content thus in the WP Editor:
    Lorem ipsum dolor sit amet, consectetur adipiscing elit. Nunc porta enim vel tellus dignissim, a venenatis neque congue. Nunc ornare cursus leo ac viverra. Pellentesque suscipit pulvinar metus, non aliquam odio egestas quis. Vestibulum porta viverra magna, vel malesuada ante fermentum vitae.
    [gallery type='picasa' user_id='kokonad' album='CorningGlassMuseum' max_results=10 layout='random' start_index=1]
    <!-- nextpage -->
    [gallery type='picasa' user_id='kokonad' album='CorningGlassMuseum' max_results=10 layout='random' start_index=11]
    <!-- nextpage -->
    [gallery type='picasa' user_id='kokonad' album='CorningGlassMuseum' max_results=10 layout='random' start_index=21]

Here is an example using the first approach. The text you provide to the more parameter controls what is shown in the button:

[gallery type='picasa' user_id='kokonad' album='CorningGlassMuseum' max_results=10 layout='circle' more='Show More']
