Generating image thumbnails using php - without running out of memory

Question

I am currently using a php gd implementation to resize images which constantly runs out of memory - rather quickly. I guess the problem are the php functions, like imagecrea

Answer 1

here is a PHP function for you

 function make_thumb($src, $dest, $desired_width,$desired_h) {

  /* read the source image */
  $source_image = imagecreatefromjpeg($src);
  $width = imagesx($source_image);
  $height = imagesy($source_image);

  $desired_height = $desired_h;

  /* create a new, "virtual" image */
  $virtual_image = imagecreatetruecolor($desired_width, $desired_height);

  /* copy source image at a resized size */
  imagecopyresampled($virtual_image, $source_image, 0, 0, 0, 0, $desired_width, $desired_height, $width, $height);

  /* create the physical thumbnail image to its destination */
  imagejpeg($virtual_image, $dest);
}
