$page =isset ($_get[' page ')? $_get[' page ']:0;//start from scratch
$imgnums = 10; Number of pictures displayed per page
$path = "Upload"; Picture saved Directory
$handle = Opendir ($path);
$i = 0;
while (false!== ($file = Readdir ($handle))) {
List ($filesname, $ext) =explode (".", $file);
if ($ext = = "gif" or $ext = = "jpg" or $ext = = "jpg" or $ext = "gif") {
if (!is_dir ('./'. $file)) {
$array []= $file;//Save picture Name

}
}
}

if ($array) {
Rsort ($array);//Modify Date reverse order
}
for ($j = $imgnums * $page; $j < ($imgnums * $page + $imgnums) && $j < $i; + + $j) {
Echo ' <div> ';
echo $array [$j], ' <br/> ';
echo "<br/> ";
Echo ' </div> ';
}
$realpage = @ceil ($i/$imgnums)-1;
$Prepage = $page-1;
$Nextpage = $page +1;
if ($Prepage <0) {
echo "Prev";
echo "<a href=?page= $Nextpage > Next </a>";
echo "<a href=?page= $realpage > last page </a>";
}elseif ($Nextpage >= $realpage) {
echo "<a href=?page=0> home </a>";
echo "<a href=?page= $Prepage > Prev </a>";
echo "Next page";
}else{
echo "<a href=?page=0> home </a>";
echo "<a href=?page= $Prepage > Prev </a>";
echo "<a href=?page= $Nextpage > Next </a>";
