Subject: Fatal Error: Allowed memory size
From: shashin@madmacs.com ("Shashin")

I am using the PHP GD functions to resize my images.
I get the following error when trying to resize multiple images. It works
for one image.

The function i am using is below
-------------------------------------------------------------------------
function Resize_Image_File ($Source_File, $Target_File, $Proportionate =
"yes", $Target_Height = "60", $Target_Width = "60", $Jpeg_Quality = "75") {

$Picture_Size = getimagesize("$Source_File");
$Source_File_Width = $Picture_Size[0];
$Source_File_Height = $Picture_Size[1];
if (preg_match("/gif/i", $Source_File)) {
$Source_File = imagecreatefromgif("$Source_File");
} else if (preg_match("/jpg|jpeg/i", $Source_File)) {
$Source_File = imagecreatefromjpeg("$Source_File");
} // end of if statement checking for images.
// we will contrain proportions for an image when not specified.
if ($Proportionate == "yes")
$Target_Height = (int)floor($Source_File_Height * $Target_Width /
$Source_File_Width);
// Create a new image object
$Target_Blank_File = imagecreatetruecolor($Target_Width, $Target_Height);
// Resize the original picture and copy it into the just created image
object.
// We will create a progressive jpeg
imageinterlace ($Target_Blank_File,1);
$Target_File_Final = imagecopyresampled($Target_Blank_File, $Source_File, 0,
0, 0, 0, $Target_Width, $Target_Height, $Source_File_Width,
$Source_File_Height);
$Create_JPEG = imagejpeg ($Target_Blank_File, "$Target_File",
$Jpeg_Quality);
imagedestroy ($Source_File);
imagedestroy ($Target_Blank_File);
imagedestroy ($Target_File_Final);
} // end of function resize image file
