imagecreatefromgif

Create a new image from file or URL (PHP 4, PHP 5)
resource imagecreatefromgif ( string filename )

imagecreatefromgif() returns an image identifier representing the image obtained from the given filename.

To ease debugging the following example will produce an error GIF:

Example 1000. Example to handle an error during creation

<?php
function LoadGif ($imgname)
{
   
$im = @imagecreatefromgif ($imgname); /* Attempt to open */
   
if (!$im) { /* See if it failed */
       
$im = imagecreatetruecolor (150, 30); /* Create a blank image */
       
$bgc = imagecolorallocate ($im, 255, 255, 255);
       
$tc = imagecolorallocate ($im, 0, 0, 0);
       
imagefilledrectangle ($im, 0, 0, 150, 30, $bgc);
       
/* Output an errmsg */
       
imagestring ($im, 1, 5, 5, "Error loading $imgname", $tc);
   }
   return
$im;
}
header("Content-Type: image/gif");
$img = LoadGif("bogus.image");
imagegif($img);
?>

The above example will output something similar to:
