Can anyone tell me how to delete these blank picassa folders in my gallery. They keep just creating and titled that days date and am not able to delete them individually? Nor can i online and delete from there? Very annoying...help please? Or should i do a complete factory reset? Thank for help.
I assume you're talking about empty albums that originate from Picasa, which is now Google+. These would be albums such as Scrapbook Photos and Instant Upload, plus others you may have created that no longer contain photos.
To delete those empty albums, you need to go to the Picasa website and log in, if needed. If you try to go to it as you used to, it will redirect you to your photos page on Google+. Therefore, you need to go to the following link instead:
This brings you to the old Picasa site. Once there, you'll see all your albums listed, including empty ones like Scrapbook Photos. Tap or click on the album you want to delete. Once that album appears, click on the Actions link shown above the album. Then click the Delete Album option.
Now, go to the Gallery app on your N7. Tap the menu button (3 vertical dots), then Refresh. The empty albums you just deleted will now be gone.
By the way, if you're not interested in being able to view your online albums, but only want to see photos stored locally on your N7, then I'd recommend using a different photo viewing app. There are quite a few to choose from on the Play Store, some free, others for a small price. I use the free QuickPic app. It's versatile and works well, though there are plenty of other apps that might be more to your liking. There are also alternative apps that allow you to view your online Picasa/Google photos, in case you don't like Gallery.
