[Plugin: NextGEN Gallery] Nextgen shortcode not working within other shortcodes

Hello i found that when i’m using the nextgen gallery’s shortcodes, within other shortcodes, images are not loading. i’m using the like locker plugin to hiding images and after the like automatically the hide content, appears, but if i have shortcode of nextgen is not loading the image but it still cites the shortcode

here an example of my article in dashboard

[wp-like-locker theme=”blue” url=”http://www.facebook.com/telalisblog.page” message=”Like to see the post”]
singlepic id=796 w=480 h=360 float=center]

[singlepic id=797 w=480 h=360 float=center]
[/wp-like-locker]

when someone likes the post it cites this

singlepic id=796 w=480 h=360 float=center]

[singlepic id=797 w=480 h=360 float=center]

and not the images.
thank you
