Recommended Posts

This is the code im am using
[code]
<form enctype="multipart/form-data" action="<?=$_SERVER['PHP_SELF']?>" method="POST">
<input type="hidden" name="MAX_FILE_SIZE" value="3000000">
Image:<br><input name="userfile" type="file"><br>
<input type="submit" name="upload" value="Upload">

<?
$uploaddir = '/usr/home/pwncae/public_html/gallery/';
$uploadfile = $uploaddir . basename($_FILES['userfile']['name']);

if(isset($_POST['upload']))
{
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
   echo "<br>File is valid, and was successfully uploaded.";
$fullurl='http://www.pwncaeks.com/gallery/'.$_FILES['userfile']['name'];

$im_file_name = $fullurl;
$image_attribs = getimagesize($im_file_name);
$im_old = imageCreateFromJpeg($im_file_name);
$th_max_width = 144;
$th_max_height = 144;
$ratio = ($width > $height) ? $th_max_width/$image_attribs[0] : $th_max_height/$image_attribs[1];
$th_width = $image_attribs[0] * $ratio;
$th_height = $image_attribs[1] * $ratio;
$im_new = imagecreatetruecolor($th_width,$th_height);
imageAntiAlias($im_new,true);
$th_file_name = '/gallery/thumbs/' . $_FILES['image_file']['name'];
imageCopyResampled($im_new,$im_old,0,0,0,0,$th_width,$th_height, $image_attribs[0], $image_attribs[1]);
imageJpeg($im_new,$im_file_name,100); }}
?>[/code]

File is valid, and was successfully uploaded.
Warning: imagejpeg(): Unable to open 'http://www.pwncaeks.com/gallery/thumbs/' for writing in /home/pwncae/public_html/dashboard/testgall2.php on line 34

sorry about the first post, the errors there arent what was actually going on, used to much bandwidth at once so it cut the image off, anyway, the above error is my problem

Does the folder ..../gallery/thumbs actually exist? Does it have the correct permissions to allow you to save files to it?
