PHP for() loop with links

Question

What I'm trying to do: create a numbered list of pictures with links to each picture. The list numbers are not consecutive.

Variables:

$image->number - gives the first number;
$image->next_pid - gives the "next link";
$image->total - gives the last number;

Code:

<?php 
$list_first = $image->number;
$list_last = $image->total;
for ($list_first = 1; $list_first <= $list_last; $list_first++) {
    echo($list_first);
}
?>

Problem: this code lists the numbered list of pictures that I need. What I can't figure out is how to include the "next link" variable into the loop.

Example: number = 1; next_pid = link_ID2; total = 7. So the list will look like this: 1 (without link) 2 (with link_ID2) 3 (link_ID3) etc. until 7. The first picture doesn't have a link because it's already showing. Sorry for not being explicit enough.

You can view what I'm trying to do here. I've listed the other pictures in that gallery but without a link. It's a wordpress site and a plugin I'm using to display the pictures in each gallery. You can view on PasteBin the functions.php of that plugin.

So this is like a pagination display, where number might contain 5, total might contain 10, and next_pid contains a link to the page that shows 11 - 15? — Alex Howansky

And can you also include a var_dump($image)? Because I can't figure out what it structure might be. — andrewsi

EDIT: This should do the trick.

<?php 

$list_last = $image->total;
for ($i = 1; $i <= $list_last; $i++)
  {
  if ($_GET['pid'] != $i) echo "<a href='http://www.noahd.net/demo-upwall/residential/rooftop-garden/15/?pid=".$i."'> ".$i." </a>";
  else echo $i;
  }
?>

The bit $list_first = $image->number; is of no use as you overwrite it shortly after in the for loop.

Added an extra line not to display a link for the current image.
