Hi all,
I have the following gallery code example found at
http://www.sitepoint.com/article/php-gallery-system-minutes
**************************
<?php
include("config.inc.php");

$result_final = "";

$gd_function_suffix = array(
'image/pjpeg' => 'JPEG',
'image/jpeg' => 'JPEG',
'image/gif' => 'GIF',
'image/bmp' => 'WBMP',
'image/x-png' => 'PNG'
);
// Fetch the photo array sent by preupload.php
$photos_uploaded = $_FILES['photo_filename'];
// Fetch the photo caption array
$photo_caption = $_POST['photo_caption'];
while( $counter <= count($photos_uploaded) )
{
if($photos_uploaded['size'][$counter] > 0)
{
if(!array_key_exists($photos_uploaded['type'][$counter], $known_photo_types))
{
$result_final .= "File ".($counter+1)." is not a photo<br />";
}
else

}
// Print Result
echo <<<__HTML_END
<html>
<head>
<title>Photos uploaded</title>
</head>
<body>
$result_final
</body>
</html>

?>
******************************
Everything works fine if I run the code locally but when I run the code on a remote server, no image is displayed in the browser.
I can see that files are loaded into "photos" directory on the server side but no image in the browser.
What is going wrong.
any suggestions.
thanks
regards
