what have 3 dimensional array... need wrap in loop..

foreach($images $imagegrouplist)     foreach($imagegrouplist $row => $value){            $gallery[] = $value['image'];     } } 

of if top level array ever has single element can iterate of

foreach($images[0] $row => $value){        $gallery[] = $value['image']; }
