If you have photos or videos in a Picasa Web Album today, the easiest way to still access, modify and share most of that content is to log in to Google Photos, and all your photos and videos will already be there. But, if in case, you do not want to use Google Photos, or you still want to be able to view specific content, such as tags, captions or comments, you can do that from the album archive page for Picasa Web Albums. It is called Album Archive (https://get.google.com/albumarchive). You can view, download, or delete your Picasa Web Albums data on this page.
To view captions at Album Archive, do the following:
- Go to Album Archive: https://get.google.com/albumarchive
- Click into an album
- Click a photo
- Click the "i" (Details) icon
- The Info panel opens up on the right side
- The Info panel closes automatically when you leave the album and you need to click "i" again when viewing another album
