I Found Solution :
$lksg_Id = '1606';
$TotalImg = get_post_meta( $lksg_Id, 'lksg_total_images_count', true );
$lksg_Gallery_Settings = "lksg_Gallery_Settings_".$lksg_Id;
$lksg_AllPhotosDetails = unserialize(base64_decode(get_post_meta( $lksg_Id, 'lksg_all_photos_details', true)));
if(count($lksg_Gallery_setting)) {
$lk_gallery_title = $lksg_Gallery_setting['lk_gallery_title'];
$lk_show_image_label = $lksg_Gallery_setting['lk_show_image_label'];
$lk_Gallery_Layout = $lksg_Gallery_setting['lk_Gallery_Layout'];
$wgp_Color = $lksg_Gallery_setting['wgp_Color'];
$lk_label_Color = $lksg_Gallery_setting['lk_label_Color'];
$lk_desc_font_Color = $lksg_Gallery_setting['lk_desc_font_Color'];
$lk_btn_Color = $lksg_Gallery_setting['lk_btn_Color'];
$lk_btn_font_Color = $lksg_Gallery_setting['lk_btn_font_Color'];
$lk_font_style = $lksg_Gallery_setting['lk_font_style'];
$lk_Custom_CSS = $lksg_Gallery_setting['lk_Custom_CSS'];
$lk_show_img_desc = $lksg_Gallery_setting['lk_show_img_desc'];
$lk_Light_Box = $lksg_Gallery_setting['lk_Light_Box'];
$lk_open_link = $lksg_Gallery_setting['lk_open_link'];
$lk_button_title = $lksg_Gallery_setting['lk_button_title'];
}
$results = array();
if($TotalImg) {
foreach($lksg_AllPhotosDetails as $data) {
$item = new stdclass();
// $item->id = $data->ID;
$item->title = $data['lksg_image_label'];
$item->content = $data['img_desc'];
$item->image = $data['lksg_image_url'];
$item->tbn = $data['lksg_img_medium'];
$results[] = $item;
}
}
// Finally Return Array As Json String
