[PHP] Image resize with database

[Steve Vernon]

(PHP 4.23, GD 1.6.2 or higher)

Hiya,
    I have code to place the picture in a database, and I normally shrink it
when the user requests a picture. What I would like it to change to is that
it should shrink or expand the picture to be 300 pixels wide and then place
it into the database. I thought the function below would work to do to
return a text resized version.

    It does sort of works, but makes a picture where only part of it is the
picture (top part), the rest is blank.

    Any help would be gr8!

    THanks,

    Steve


 function shrink_picture($tmp_name,$size,$name)
 {
  $result = ereg(".gif$",strtolower($name));

  if($result)
  {
   $img = imagecreatefromgif($tmp_name);

  }
  else
  {
   $img = imagecreatefromjpeg($tmp_name);
  }

  $width = imagesx($img);
  $height = imagesy($img);
  $new_height = abs(300.0 * ($height/$width));

  $new_img = imagecreate(300, $new_height );


imagecopyresized($new_img,$img,0,0,0,0,300,$new_height,imagesx($img),imagesy
($img));

  imagejpeg($new_img,$tmp_name."a",70);

  imagedestroy($new_img);
  imagedestroy($img);

  $data = addslashes(fread(fopen($tmp_name."a","r"),$size));

  return $data;
 }
