                     $query = $dbconn->query("select * from `uploading`") or die(mysqli_error());
                     while($fetch = $query->fetch_array()){
                                       ?>

                    <a class="gallery-item" href="artifactimage/<?php echo $fetch['artifact_image']; ?>" title="<?php echo $title ?>" data-gallery>
                        <div class="image">

                                <?php echo $fetch['artifact_desc']; ?></span>
                        </div>
