array element printing control

[kumarsena]

hey,

All you need is a for loop and a variable telling the page which image to start on:

<?PHP
$NUMPERPAGE = 12;
if (!$index) $index = 0;
for ($i=1; $i <= $NUMPERPAGE; $i++) {
echo "<P>Displaying image " . ($index+$i) . "</P>";
}
?>

Then your links can be:

gallery.html
gallery.html?index=12
gallery.html?index=24
...
