Custom Thumbnail problem

[eluser]Ray G[/eluser]
I have a file called imageresize.php which generates thumbnail images

Code:

header('Content-type: image/jpeg');
function resampleimage($maxsize, $sourcefile, $imgcomp=0){
// SET THE IMAGE COMPRESSION
$g_imgcomp=100-$imgcomp;
  // CHECK TO SEE IF THE IMAGE EXISTS FIRST
  if(file_exists($sourcefile)){
  // FIRST WE GET THE CURRENT IMAGE SIZE
  $g_is=getimagesize($sourcefile);
    /********* CALCULATE THE WIDTH AND THE HEIGHT ***************/
    // CHECK TO SEE IF THE WIDTH AND HEIGHT ARE ALREADY SMALLER THAN THE MAX SIZE
    if($g_is[0] <= $maxsize && $g_is[1] <= $maxsize){
    // LEAVE WIDTH AND HEIGHT ALONE IF IMAGE IS SMALLER THAN MAXSIZE
    $new_width=$g_is[0];
    $new_height=$g_is[1];
    } else {
    // GET VALUE TO CALCULATE WIDTH AND HEIGHT
    $w_adjust = ($maxsize / $g_is[0]);
    $h_adjust = ($maxsize / $g_is[1]);
      // CHECK TO WHICH DIMENSION REQUIRES THE SMALLER ADJUSTMENT
      if($w_adjust <= $h_adjust){
      // CALCULATE WIDTH AND HEIGHT IF THE WIDTH VALUE IS SMALLER
      $new_width=($g_is[0]*$w_adjust);
      $new_height=($g_is[1]*$w_adjust);
      } else {
      // CALCULATE WIDTH AND HEIGHT IF THE HEIGHT VALUE IS SMALLER
      $new_width=($g_is[0]*$h_adjust);
      $new_height=($g_is[1]*$h_adjust);
      }
    }
  //SEARCHES IMAGE NAME STRING TO SELECT EXTENSION (EVERYTHING AFTER THE LAST "." )
    $image_type = strrchr($sourcefile, ".");

    //SWITCHES THE IMAGE CREATE FUNCTION BASED ON FILE EXTENSION
    switch($image_type) {
        case '.jpg':
            $img_src = imagecreatefromjpeg($sourcefile);
            break;
        case '.jpeg':
            $img_src = imagecreatefromjpeg($sourcefile);
            break;
        case '.png':
            $img_src = imagecreatefrompng($sourcefile);
            break;
        case '.gif':
            $img_src = imagecreatefromgif($sourcefile);
            break;
        default:
            echo("Error Invalid Image Type");
            die;
            break;
    }
  // CREATE THE TRUE COLOR IMAGE WITH NE WIDTH AND HEIGHT
  $img_dst=imagecreatetruecolor($new_width,$new_height);
  // RESAMPLE THE IMAGE TO NEW WIDTH AND HEIGHT
  imagecopyresampled($img_dst, $img_src, 0, 0, 0, 0, $new_width, $new_height, $g_is[0], $g_is[1]);
  // OUTPUT THE IMAGE AS A JPEG.
  // THIS CAN BE CHANGED IF YOU WANT TRANSPARENCY OR PREFER ANOTHER FORMAT. MAKE SURE YOU CHANGE HEADER ABOVE.
  imagejpeg($img_dst);
  // DESTROY THE NEW IMAGE
  imagedestroy($img_dst);
  return true;
  } else {
  return false;
  }
}
// NOW CALL THE IMAGE FROM ANY OTHER PAGE WITH <img src="imageresize.php?maxsize=xxx&source=path/to/image/file" /> xxx=a value for the max size
resampleimage($_GET['maxsize'], $_GET['source']);
?&gt;

I have a function which queries mysql and returns image info then creates the html to show the thumbnail (shortened)

Code:

$images[] = '
          <a >filepath.'" rel="lightbox['.$row->cat.']" border="1">
            <img >filepath.'" border="0" alt="'.$row->fname.'" >
          </a>'."<br />";

Above code is not displaying correctly but it will produce something like this

Code:

<a href="/images/gallery/Test_Image.jpg" rel="lightbox[Forms]" border="1">
            <img src="imageresize.php?maxsize=150&source;=./images/gallery/Test_Image.jpg" border="0" alt="Test Image" >
          </a>

Now if I go to my page all I get is the alt tag instead of the thumbnail image. If I go to my browser and just put in
http://mysite.com/imageresize.php?maxsiz..._image.jpg
It works fine.
I tried the url/querystring fix but not working either

thanks in advance for the help
