Below is a sample code that I used, but I'm not sure of the security issue for this.
You have to set the permission of your destiny folder to be writtable (eg 777)

<form enctype="multipart/form-data" method="post" action=" <?php echo $PHP_SELF ?>">

<!-- max_file_size in bytes -->
<INPUT TYPE="hidden" name="MAX_FILE_SIZE" value="1024000">

file<br><input type="File" name="picture" size="25"><br><br>
<input type="submit" name="submit" value="Upload">

</form>

<?php

if ($submit) {

require("library/phpobjects.php3");
$sql=new MySQL_class;
$sql->Create("fm");	

echo $picture_name;
echo "<br>"; 

$sql->Insert("INSERT INTO table (picture) VALUES ('$picture')");
$affected_rows=$sql->a_rows;


$size = GetImageSize("$picture");
echo $size[3];

exec( "mv $picture /test/picture_name"); 

echo  "temp file: $picture<br>\n"; 
echo  "file name: $picture_name<br>\n"; 
echo  "file size: $picture_size<br>\n"; 
echo  "file type: $picture_type<br>\n"; 
echo  "<br>\n"; 
echo  "<img src=test/$picture_name><br>\n"; 

}

?>

if you look at phpinfo() on your site, you'll see an entry called 'safe-mode'

AFAIK, if this is set to 'on', then you can't do uploads. Basically you'll be trying to copy/move a file owned by userid xxx (perhaps 'nobody', the web user) in the temp file area to a directory owned by you, and it will squeal.

I got this error on one of my websites. Funny, I could upload via a perl script so having safe-mode set on seemed irrelevant unless it has another purpose.

Maybe someone more knowledgeable could comment.
