imagecreatefromjpeg() hangs

Scotty2024 · November 6, 2009

I am having problems with imagecreatefromjpeg() hanging up while uploading files ~400 KB or larger. Am I doing anything wrong? Here is an example for jpg files:

upload form

<form action="upload.php" method="post" enctype="multipart/form-data">
Picture: <input name="userfile" type="file" id="userfile">
<br />
<input type="submit" name="uploadPic" value="Upload" />
</form>

upload.php

if(isset($_POST['uploadPic']))
{
   $image = $_FILES['userfile']; //assuming user did upload an image. error checking not shown.
   
   switch($image['type'])
   {
      case "image/pjpeg":
      case "image/jpg":
      case "image/jpeg":
         jpg_processing($image);
         break;
      //case gif and png...
}

function jpg_processing($picture)
{	
$fileName = $picture['name'];
$tmpName  = $picture['tmp_name'];
$fileSize = $picture['size'];
$fileType = $picture['type'];
$size = getimagesize($tmpName);

         //Resize image to correct size
        if($size[0] > $size[1]) //width > height
{
	if($size[0] > 604)
	{
		$h_max = ($size[1] * 604)/$size[0];
		$w_max = 604;
	}
	else
	{
		$h_max = $size[1];
		$w_max = $size[0];
	}
}
else if($size[0] < $size[1])
{
	if($size[1] > 604)
	{
		$w_max = ($size[0] * 604)/$size[1];
		$h_max = 604;
	}
	else
	{
		$h_max = $size[1];
		$w_max = $size[0];
	}
}
else if($size[0] == $size[1])
{
	if($size[0] > 604 && $size[1] > 604)
	{
		$h_max = 604;
		$w_max = 604;
	}
	else
	{
		$h_max = $size[1];
		$w_max = $size[0];
	}
}

$w = $size[0];
$h = $size[1];

$x_ratio = $w_max/$w;
$y_ratio = $h_max/$h;

if ($w <= $w_max && $h <= $h_max)
{
	$w_tn=$w;
	$h_tn=$h;
}
else if (($x_ratio * $h) < $h_max)
{
	$h_tn=ceil($x_ratio*$h);
	$w_tn=$w_max;
}
else
{
	$w_tn = ceil($y_ratio * $w);
	$h_tn=  $h_max;
}
        //done with resizing

        $src = imagecreatefromjpeg($tmpName); //THIS LINE hangs! Doesn't make it past here.
$dst = imagecreatetruecolor ($w_tn, $h_tn);
imagecopyresized($dst, $src, 0, 0, 0, 0, $w_tn, $h_tn, $w,$h);
imageinterlace($dst, 1);

$out_file= '/pictures/'. mt_rand() . '.jpg';
$location = 'http://website.com' . $out_file;

imagejpeg ($dst, $out_file, 100);
}

I don't know why it hangs up on imagecreatefromjpeg(). The browser is blank and simply shows "Done" in the status bar. I have read that this happens if the image doesn't have an EOF tag. I have tried several different images and it still hangs. However, if I upload small images like ~100 KB or less, it works. :confused:

Do I have an error in my code I am over loooking?

Thanks!

Here is an update. I am pretty sure that the script works for all images. I tried it on a different server with the same images and everything worked as it should. I now believe that it is the fault of the server. This script is failing on 1and1.com servers (I am not a fan of this company).

I know that the GD Graphics Library is required for this script. To make sure the library is installed I tried phpinfo(); (in info.php) but that also fails on this server. For some reason it pulls my css style sheet, header graphic and required navigation php file. I have no clue why or how it gets all that when all I have is <?PHP phpinfo(); ?> in the info.php file.

Can anyone tell me if 1and1.com has the GD graphics library installed and what version? Also, why does this script fail for large images (~400 KB or larger) on 1and1.com servers and not other servers? 1and1 is definitely frustrating!

Better yet, can anyone tell me how to upload and resizes images a different way that 1and1 will like?

Thanks for any help!

I tried a simple upload script without the resizing just to see if I could upload images larger than 400 KB. The script below works, however I don't know how to resize the image which is required for my application. Can anyone help me adapt this script below to resize the image?

<?php
if ($_REQUEST[completed] == 1)
{
$newname = uniqid("whc").".jpg";
move_uploaded_file($_FILES['mailfile']['tmp_name'], "pictures/$newname");
}
?>
<html>
<head><title>Upload page</title></head>
<body><h1>Image Uploader</h1>
<?php
if ($_REQUEST[completed] != 1) 
{ 
?>
<b>Please upload an image</b><br>
<form enctype=multipart/form-data method=post>
<input type=hidden name=MAX_FILE_SIZE value=1500000>
<input type=hidden name=completed value=1>
Picture: <input type=file name=mailfile><input type=submit></form>
<?php
}
else
{
?>
	<b>Uploaded!</b>
<?php
}
?>
</body>
</html>
