Cambiar tamaño de thumb en php

[alvaro0022]

Para explicarme bien lo que quiero hacer es lo siguiente:

Tengo un codigo que crea una tabla con thum. lo que quiero es cambiar el tamaño de esos thum a 100x100. Pero como no se casi nada de php no tengo idea de como hacerlo.

Aqui dejo el codigo.

Código:

<?php

$cat_match_sql = ($cat_id && check_permission("auth_viewcat", $cat_id)) ? "AND i.cat_id = '$cat_id' " : "";
$register_array = array();

$cat_id_sql = get_auth_cat_sql("auth_viewcat", "NOTIN");

$lang_top_image_hits = $lang['top_image_hits'];

// Hits
$sql = "SELECT i.image_id, i.user_id, i.cat_id, i.image_name, i.image_hits, i.image_thumb_file, i.image_media_file, c.cat_name".get_user_table_field(", u.", "user_name")."
FROM (".IMAGES_TABLE." i, ".CATEGORIES_TABLE." c)
LEFT JOIN ".USERS_TABLE." u ON (".get_user_table_field("u.", "user_id")." = i.user_id)
WHERE i.image_active = 1 AND i.cat_id NOT IN ($cat_id_sql) AND i.cat_id = c.cat_id
$cat_match_sql
ORDER BY i.image_hits DESC, i.image_name ASC
LIMIT 10";
$result = $site_db->query($sql);
$top_list = array();
$i = 1;
while ($row = $site_db->fetch_array($result)) {
$top_list[$i] = $row;
$i++;
}
$site_db->free_result();
