Resize large image

[satal keto]

Hello I am trying to get some code which will resize images which are uploaded to my website using a form.

The code I am using to resize the images atm is

function createThumbnail($imageDirectory, $imageName, $thumbDirectory, $thumbHeight)
{
$srcImg = imagecreatefromjpeg("$imageDirectory/$imageName");
$origWidth = imagesx($srcImg);
$origHeight = imagesy($srcImg);

$ratio = $origHeight / $thumbHeight;
$thumbWidth = $origWidth / $ratio;
$dst_img=ImageCreateTrueColor($thumbWidth,$thumbHeight);
#imagecopyresampled($dst_img,$srcImg,0,0,0,0,$thumbWidth,$thumbHeight,$origWidth,$origHeight);
imagecopyresized($dst_img,$srcImg,0,0,0,0,$thumbWidth,$thumbHeight,$origWidth,$origHeight);
imagejpeg($dst_img,$thumbDirectory . "/" . $imageName);
imagedestroy($dst_img);
}

The problem is when ever I try to run this code it is saying...

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 3264 bytes) in K:\WOS Stuff\www\sb\adminPhotos.php on line 5

where line 5 is

$srcImg = imagecreatefromjpeg("$imageDirectory/$imageName");

I was wondering whether anyone had any idea's of some how that I would be able to resize the images without causing this error?

Change

 

$srcImg = imagecreatefromjpeg("$imageDirectory/$imageName");

 

to

 

$srcImg = imagecreatefromjpeg("YOUR_PATH/".$imageName);

 

But replace YOUR_PATH with your direct path. Because there could be an error with the $imagedirectory variable.

 

Just a thought

No unfortunately its not that I am using the wrong file, it gives the same result using both versions.

Well it could also be that your script grabs just over the 8MB default memory limit of PHP. (although i think php5 has a default limit of 300mb).

 

What version of php are you running?

 

Run phpinfo() and check your version, also check your memory limit. You can edit memory_limit in your php.ini file to fix this, or you could edit your .htaccess file and add this line:

php_value memory_limit 24M for a quick fix, if thats the problem
