Please help displaying image after upload

Hi,

I am uploading an image to a folder and I need to display the uploaded image in a new page.

This is my code for the upload:

<?php
//define a maxim size for the uploaded images in Kb
define ("MAX_SIZE","2000000"); 

//This function reads the extension of the file. It is used to determine if the
// file is an image by checking the extension.
function getExtension($str) {
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}

//This variable is used as a flag. The value is initialized with 0 (meaning no 
// error found) 
//and it will be changed to 1 if an errro occures. 
//If the error occures the file will not be uploaded.
$errors=0;
//checks if the form has been submitted
if(isset($_POST['upload'])) 
{
//reads the name of the file the user submitted for uploading
$image=$_FILES['image']['name'];
//if it is not empty
if ($image) 
{
//get the original name of the file from the clients machine
$filename = stripslashes($_FILES['image']['name']);
//get the extension of the file in a lower case format
$extension = getExtension($filename);
$extension = strtolower($extension);
//if it is not a known extension, we will suppose it is an error and 
// will not upload the file, 
//otherwise we will do more tests
if (($extension != "jpg") && ($extension != "jpeg") && ($extension !=
"png") && ($extension != "gif")) 
{
//print error message
echo '<h1>Tipo de imagen no permitido.</h1>';
$errors=1;
}
else
{
//get the size of the image in bytes
//$_FILES['image']['tmp_name'] is the temporary filename of the file
//in which the uploaded file was stored on the server
$size=filesize($_FILES['image']['tmp_name']);

//compare the size with the maxim size we defined and print error if bigger
if ($size > MAX_SIZE*1024)
{
echo '<h1>La imagen es demasiado grande.</h1>';
$errors=1;
}

//we will give an unique name, for example the time in unix time format
$image_name=time().'.'.$extension;
//the new name will be containing the full path where will be stored (images 
//folder)
$newname="banners/".$image_name;
//we verify if the image has been uploaded, and print error instead
$copied = copy($_FILES['image']['tmp_name'], $newname);
if (!$copied) 
{
echo '<h1>Error al subir la imagen.</h1>';
$errors=1;
}}}

//If no errors registred, print the success message
if(isset($_POST['Submit']) && !$errors) 
{
echo "<h1>La imagen se ha cargado correctamente</h1>";
}
$query = "INSERT INTO banner_rotator.t_banners (banner_path) ".
"VALUES ('$newname')";
mysql_query($query) or die('Error, query failed : ' . mysql_error()); 

//echo "<br>Files uploaded<br>";

header("Location: PC_cropbanner.php"); 
}

Sowhat I need to do is to display the uploaded image in PC_cropbanner.php.

How can I do this?

You could pass the image name using your redirect:

 

header("Location: PC_cropbanner.php?image=".$image_name);

 

Then, at the top of PC_copbanner.php:

$image_name = $_GET['image'];

 

You will need to check that the image variable has a value...
