Google-photos – How to save a photo including location from a shared album or even see the location

No you cannot do this on Google Photos.

--Update--
Not a chance with Google now, they are shutting down Picasa at 1st May.

This option is only available on Picasa web album. Google Drive does have an option to block the download link in the "advance" section of the share settings, and it will create a new Picasa album with uploaded photos automatically. However, you cannot edit such album on Picasa and will get a "500 Internal Server error" when you try. So you may want to upload your photos to Picasa directly.

Since Google Plus is shutting down in April 2019, I was looking for a replacement to share multiple shared albums via one URL (one page). And the solution I found is this:

1. create a new site using https://sites.google.com
2. from the Insert pane, click Embed
3. in Google Photos,
   • open your shared album,
   • click the share icon,
   • click Create link and Copy the URL, which should look like https:// goo.gl/photos/_hash_
4. back on your new Site in the Insert/Embed dialog paste the URL of the album, it previews your thumbnail and you Insert it into the page.
5. Done.
