How to delete synced photos in gallery? android ?

Just got a note 2, love it! i accidentally synced my gallery with Facebook and now cant delete the albums??? i turned sync off but they didn't magically disappear. when you select them there is no trash can that appears. thanks for any help!

here is a fastest way to delete gallery photos they come from sync with google account.

once you disable auto sync then follow this step:

1. go to setting > application manager > all apps > gallery
2. Tap clear data and clear Cache    

You are Done !!
