image work

i was looking at some php tutorial about water marking images on the fly. i dont know much about it yet, but is it possible to take an image and reduce the smallest length to 65px and keep it proportional and bascically make a thumbnail?

this is a function i wrote to upload an image, create a thumb with a height of 80 and resizes the width proportionately. it upload the image and names the thumb with a _t at the end. hope this helps.

$filename would be the temporary file name ( $_FILES['somefile']['tmp_name'] )
$name would be what you want it to be named

PHP Code:

<?
function getRootPath(){
  return "/home/user/public_html/";
}

function uploadPhoto($filename,$name){
  $name = stripslashes($name);
  list($width, $height) = getimagesize($filename);
  
  $percent = 80 / $height;
  
  $new_width = $width * $percent;
  $new_height = $height * $percent;
  
  // Resample
  $image_p = imagecreatetruecolor($new_width, $new_height);
  $image = imagecreatefromjpeg($filename);
  imagecopyresampled($image_p, $image, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
  
  $newfile = getRootPath()."images/photos/".$name;
  move_uploaded_file($filename,$newfile);
  chmod($newfile, 0644);
  
  $array = explode(".",$name);
  imagejpeg($image_p, getRootPath()."images/photos/".$array[0]."_t.".$array[1]);
}
?>
