Resizing an Image on upload

[coolphpdude]

Hi there, i have previously posted a request for help on this matter but i am still struggling so i have launched a new topic on it. I want my user to upload a picture regardless of size, i want the original pic to be resized and also a smaller thumbnail created. i have been trying to work through some code provided to me previously but im still stuck. I have posted my code below.

 

I have taken out any irrelevant crap. Thanks for your help!

 

<?php
session_start();

// Take the sessions into variables
$user_session_id =$_SESSION['user_session_id'];
$user_session_password =$_SESSION['user_session_password'];

$upload=$_POST["upload"];


// ********************************* code given when i previously requested help
function resampleimage($maxsize, $sourcefile, $destination, $imgcomp=0){
// SET THE IMAGE COMPRESSION
$g_imgcomp=100-$imgcomp;
  // CHECK TO SEE IF THE IMAGE EXISTS FIRST
  if(file_exists($sourcefile)){
  // FIRST WE GET THE CURRENT IMAGE SIZE
  $g_is=getimagesize($sourcefile);
    /********* CALCULATE THE WIDTH AND THE HEIGHT ***************/
    // CHECK TO SEE IF THE WIDTH AND HEIGHT ARE ALREADY SMALLER THAN THE MAX SIZE
    if($g_is[0] <= $maxsize && $g_is[1] <= $maxsize){
    // LEAVE WIDTH AND HEIGHT ALONE IF IMAGE IS SMALLER THAN MAXSIZE
    $new_width=$g_is[0];
    $new_height=$g_is[1];
    } else {
    // GET VALUE TO CALCULATE WIDTH AND HEIGHT
    $w_adjust = ($maxsize / $g_is[0]);
    $h_adjust = ($maxsize / $g_is[1]);
      // CHECK TO WHICH DIMENSION REQUIRES THE SMALLER ADJUSTMENT
      if($w_adjust <= $h_adjust){
      // CALCULATE WIDTH AND HEIGHT IF THE WIDTH VALUE IS SMALLER
      $new_width=($g_is[0]*$w_adjust);
      $new_height=($g_is[1]*$w_adjust);
      } else {
      // CALCULATE WIDTH AND HEIGHT IF THE HEIGHT VALUE IS SMALLER
      $new_width=($g_is[0]*$h_adjust);
      $new_height=($g_is[1]*$h_adjust);
      }
    }
  //SEARCHES IMAGE NAME STRING TO SELECT EXTENSION (EVERYTHING AFTER THE LAST "." )
$image_type = strrchr($sourcefile, ".");

//SWITCHES THE IMAGE CREATE FUNCTION BASED ON FILE EXTENSION
switch($image_type) {
	case '.jpg':
		$img_src = imagecreatefromjpeg($sourcefile);

  imagecopyresampled($img_dst, $img_src, 0, 0, 0, 0, $new_width, $new_height, $g_is[0], $g_is[1]);
  // OUTPUT THE IMAGE AS A JPEG.
  // THIS CAN BE CHANGED IF YOU WANT TRANSPARENCY OR PREFER ANOTHER FORMAT. MAKE SURE YOU CHANGE HEADER ABOVE.
  imagejpeg($img_dst, $destination, 100);
  // DESTROY THE NEW IMAGE
  imagedestroy($img_dst);

update...

 

I have that code kind of working, however when you go back into the page that displays the pic that the user has uploaded, you need to hit refresh on the broser to see the new image in its resampled size... any ideas???
