note 31178 added to function.imagecreatefromstring

Here is the code I did to create a thumbnail image from the database blob field. The trick is to use "imagecreatefromstring()" to create an image file. Jack Shieh <?php require("dbconfig.inc"); $id = $_GET['id']; if($id) { $link = @mysql_connect($host, $user, $password) or die("Could not connect: " . mysql_error()); @mysql_select_db($dbname, $link); $query = "select filetype, image from pictures where id = $id"; $result = @mysql_query($query); $data = @mysql_result($result,0,"image"); $type = @mysql_result($result,0,"filetype"); Header( "Content-type: $type"); $size = 150; // new image width $src = imagecreatefromstring($data); $width = imagesx($src); $height = imagesy($src); $aspect_ratio = $height/$width; if ($width <= $size) { $new_w = $width; $new_h = $height; } else { $new_w = $size; $new_h = abs($new_w * $aspect_ratio); } $img = imagecreatetruecolor($new_w,$new_h); imagecopyresized($img,$src,0,0,0,0,$new_w,$new_h,$width,$height); // determine image type and send it to the client if ($type == "image/pjpeg") { imagejpeg($img); } else if ($type == "image/x-png") { imagepng($img); } else if ($type == "image/gif") { imagegif($img); } imagedestroy($img); mysql_close($link); }; ?> -- http://www.php.net/manual/en/function.imagecreatefromstring.php http://master.php.net/manage/user-notes.php?action=edit+31178 http://master.php.net/manage/user-notes.php?action=delete+31178 http://master.php.net/manage/user-notes.php?action=reject+31178
