Hi;

I got a problem to output resize image after i check the type of image.
Could anyone help me, thanks.

The test_1.php has not problem to output image, but the test_2.php could not output image.

test_1.php

Code: 
<?php
$image=$_GET['image'];
// The file
$filename = '../images/thread_images/'. $image;

// Set a maximum height and width
$width = 200;
$height = 200;

// Content type
header('Content-Type: image/jpeg');


// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);

$ratio_orig = $width_orig/$height_orig;

if ($width/$height > $ratio_orig) {
   $width = $height*$ratio_orig;
} else {
   $height = $width/$ratio_orig;
}

// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

// Output
imagejpeg($image_p, null, 100);


?>


test_2.php

Code: 
<?php
$image=$_GET['image'];
// The file
$filename = '../images/thread_images/'. $image;

// Set a maximum height and width
$width = 200;
$height = 200;

// Content type

if(exif_imagetype($image)==IMAGETYPE_JPEG)
  header('Content-Type: image/jpeg');
else if(exif_imagetype($image)==IMAGETYPE_GIF)
  header('Content-Type:image/gif'); 


// Get new dimensions
list($width_orig, $height_orig) = getimagesize($filename);

$ratio_orig = $width_orig/$height_orig;

if ($width/$height > $ratio_orig) {
   $width = $height*$ratio_orig;
} else {
   $height = $width/$ratio_orig;
}

// Resample
$image_p = imagecreatetruecolor($width, $height);
$image = imagecreatefromjpeg($filename);
imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

// Output


  if(exif_imagetype($imagepath)==IMAGETYPE_JPEG)
    imagejpeg($image_p, null, 100);
  else if(exif_imagetype($imagepath)==IMAGETYPE_GIF)
     imagegif($image_p, null, 100); 

?>

Hi

What is $imagepath's value ? Are you sure you not $filename what you intended to use ? ( Including the [tt]header()[/tt] call's [tt]if[/tt] condition too. )

Code: 
if(exif_imagetype($filename)==IMAGETYPE_JPEG)
  header('Content-Type: image/jpeg');
else if(exif_imagetype($filename)==IMAGETYPE_GIF)
  header('Content-Type:image/gif'); 


  if(exif_imagetype($filename)==IMAGETYPE_JPEG)
    imagejpeg($image_p, null, 100);
  else if(exif_imagetype($filename)==IMAGETYPE_GIF)
     imagegif($image_p, null, 100);
