Hi,

I investigate a bit on Picasa Web Album API 3 and my understanding is that not all API are deprecated. According to FAQ:
https://developers.google.com/picasa-web/faq

There was an announcement posted on February 12, 2016 stating that the work to retire Picasa would begin on May 1, 2016. As part of that work, Picasa Web Albums will be deprecated. However, the Picasa Web Albums Data API will continue to work with some changes. These changes are detailed in the release notes of the new version of the API.

In the release notes I read:

On February 12, 2016 we announced that Picasa Web Albums and the Picasa desktop application would be retired. As part of that announcement, there were also changes to the Picasa Web Albums Data API. Specifically, the API would no longer support the following functionality:

• Flash support
  
  
• Community search
  
  
• Mutation operations other than uploads
  
  
• All support for tags, comments, contacts, and featured photos
  

So basically it's still possible see albums, photos stream, photos in albums, upload image and download image. Tags are not supported but this is not a drama.
The only thing probably that cannot be done (and the plugin does not use it) is to update a photo and is useful when you have a synchronize thread that keep remote photos in sync with a local folder a feature that I would like to have.

However, here the main issue seems to be that the author is not interested any more in maintaining this code. Hope someone else want to continue this work.

If you scroll through the thread you will find the problem that led the plugin to get depreciated was fact that the API stopped allowing people to authenticate.  If you have a token already, it continued to work.  If you were using the API for the first time, then you couldn't get past this entry point of getting authenticated.   Maybe Google finally decided to fix this.
