It may be slightly easier to just limit the display to the previous and
next X pages, with the current one being in the middle. In which case,
you could replace:
> for($i = 1 ; $i <= $NumberOfPages ; $i++) {
with:
$displayWindow = 3;
for($i = $page-$displayWindow ; $i <= $page+$displayWindow ; $i++) {
if (($i > 0) && ($i <=$NumberOfPages)){
If you limit the pages shown, however, be sure to include a link to go
back to page 1, and, optionally, go to the end
