View Facebook photo comments from Photos & Videos app [webOS 3.x] 10
This tip is only for devices running webOS 3.0 and higher
While you can always view your Facebook photos using the web browser or within the TouchPad's Facebook app, did you know that you can also see all the comments of your pictures directly in the Photos & Videos app on the TouchPad, providing that you have Facebook photos sync enabled?. If you do not have Facebook photos sync enabled, go to the Accounts app and turn it on. Then, just open the Photos & Videos app and find the album that contains the photo and then tap on the photo itself. You will be able to tell it's a Facebook photo album because it has a icon on the album's thumbnail
After loading up the photo, you should see the onscreen controls across the bottom of the screen. If you do not see the photo controls, just tap the photo once. On the bottom-right of the screen, you should see a icon that, when tapped, will show you all the comments on that picture along with when the comments was left. You can even add your own right from the app.
Note that if you have added multiple Facebook accounts to your TouchPad, there will not be any indicator as to which account the album belongs to. And, if you were to add your own comment to a photo, it will automatically use the account that owns the album.
