Help with php image uploader coding

[tazfellow]

Heya,

I've been trying to work on creating thumbnail img uploaders... Im wanting to make the coding output aka the echo after uploading the image come out with the following result:

Full size Image: [img]http://main website address here[/img]

Thumnail Image: [url=http://main website address here][img=100x50]http://main website address here[/img][/url]  

The current code I have is the following:

<?php

if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 5000000))
 {
 if ($_FILES["file"]["error"] > 0)
   {
   echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
   }
 else
   {
       
   if (file_exists("upload/" . $_FILES["file"]["name"]))
     {
     echo $_FILES["file"]["name"] . "File name already exists!";
     }
   else
     {
     move_uploaded_file($_FILES["file"]["tmp_name"],
     "upload/" . $_FILES["file"]["name"]);
     echo "[img]http://main website address here/" . "upload/" . $_FILES["file"]["name"];
     }
   }
 }
else
 {
 echo "Invalid file";
 }
?>[/img]</font></center></body>

What do I need to change in the above to make echo that first code. I'd appreciate all the help I can get in this

<?php

if (
in_array($_FILES['file']['type'], Array('image/gif', 'image/jpeg', 'image/pjpeg', 'image/png')) &&
$_FILES['file']['size'] < 5000000
)
{
if ($_FILES['file']['error'])
echo 'Error: ', $_FILES['file']['error'];
else if (file_exists('./upload/' . $_FILES['file']['name']))
echo 'Error: ', htmlentities($_FILES['file']['name']), ' already exists!';
else
{
move_uploaded_file($_FILES['file']['tmp_name'], './upload/' . $_FILES['file']['name']);
$url = 'http://' . $_SERVER['HTTP_HOST'] . '/upload/' . $_FILES['file']['name'];
echo '<p>Full Size Image: [img]', $url, '[/img]</p>',
'<p>[url=', $url, '][img=100x50]', $url, '[/img][/url]</p>';
}
}
else
echo 'Invalid file type or size.';
?>

I recommend you learn PHP before using a script like this, though. There are plenty of free hosts around that can accomplish the same goal with less bandwidth and hosting cost to you, e.g. imgur.

I am learning gradually as I go. Probably not the most recommended method but its how I learnt html
