A simple method to resize a image keeping the constraint proportions:
<?php
// Constraints
$max_width = 100;
$max_height = 100;
list($width, $height) = getimagesize($img_path);
$ratioh = $max_height/$height;
$ratiow = $max_width/$width;
$ratio = min($ratioh, $ratiow);
// New dimensions
$width = intval($ratio*$width);
$height = intval($ratio*$height);
?>
