I'm not quite sure what the problem is - you'll have to be a little bit more specific.

Is the problem that you don't know how? Or do you know how, and you're getting an error message? Or is there no error message, it just doesn't save it twice? Do you have example code?

Theoretically, it should work. You do the code to upload the image. Then you use one of the output functions (imagegif, imagepng, etc) to save the image to a file. Then you resize the image, and use an output function to save it again, as a different file.

This is the start of my code... it does not upload twice to start wiht... once i've got it to upload twice i'll resize the image in the thumbs folder... if that is okay??

<?php
header('Content-type: image/jpeg');

$uploaddir = '/home/httpd/vhosts/msite.com/httpdocs/travel/album/';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
   echo "Orig Upload.\n";
} else {
   echo "Possible file upload attack orig!\n";
}


$uploadthumbdir = '/home/httpd/vhosts/msite.com/httpdocs/travel/album/thumbs/';
$upload2file = $uploadthumbdir . basename($_FILES['userfile']['name']);
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $upload2file)) {
   echo "Thumb Uploaded.\n";
} else {
   echo "Possible file upload attack thumb!\n";
}


?>

Ah, ok, now I have a better picture. There's no need to upload the image twice. Here's what you can do.

You upload the image, and save it to a file. So far, you're good. Then, instead of uploading it again, you need to open it with a GD function. (Hopefully your server has GD installed). Depending on the format of the image, you'll have to use either imagecreatefromgif(), imagecreatefromjpeg(), imagecreatefrompng(), or imagecreatefromwbmp(). Once you have loaded the image, you can do your resizing operations with imagecopyresampled(). Finally, you save the image in its new location with either imagegif(), imagejpeg(), imagepng(), or imagewbmp() once again depending on the format of the image.

Hi,

<?php
header('Content-type: image/jpeg');

$uploaddir = '/home/httpd/vhosts/site.com/httpdocs/travel/album/';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
   echo "Orig Upload.\n";
} else {
   echo "Possible file upload attack orig!\n";
}


$location = 'http://www.site.com/travel/album/';
$imgname = $location . basename($_FILES['userfile']['name']);

echo $imgname;

function LoadJpeg($imgname) 
{
   $im = @imagecreatefromjpeg($imgname); /* Attempt to open */
   if (!$im) { /* See if it failed */
       $im  = imagecreatetruecolor(150, 30); /* Create a black image */
       $bgc = imagecolorallocate($im, 255, 255, 255);
       $tc  = imagecolorallocate($im, 0, 0, 0);
       imagefilledrectangle($im, 0, 0, 150, 30, $bgc);
       /* Output an errmsg */
       imagestring($im, 1, 5, 5, "Error loading $imgname", $tc);
   }
   return $im;
}


$filename = $im;
$percent = 0.5;


// Get new dimensions
list($width, $height) = getimagesize($filename);
$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);

// Output
imagejpeg($image_p, null, 100);

?>

I get this error
