help with converting image resize script from image magic to gd

[aron]

Hi All, i have made this script already using imagemagic, but have just relised the server runs gd librarys, i know this script works in image magic (i have used it elsewhere) was wondering if somone could help me convert it to use gd please.

//Image Magick
$rndnum = rand(10,999999);
exec("C:\\imagemagick\\convert.exe -resize 800 ".$new_file." ".$path.$rndnum.$id."minus_01".".jpg");
exec("C:\\imagemagick\\convert.exe -resize 420 ".$new_file." ".$path.$rndnum.$id."minus_02".".jpg");
exec("C:\\imagemagick\\convert.exe -resize 105 ".$new_file." ".$path.$rndnum.$id."minus_03".".jpg");
exec("C:\\imagemagick\\convert.exe -resize 72 ".$new_file." ".$path.$rndnum.$id."minus_04".".jpg");
$dbsave = $rndnum.$id;
//print "<br>Thumbnail: ".$path."thumb".$rndnum.".jpg";

//deletes original image
unlink($new_file);

thats the image magic resize bit.

if you need the entire script here it is.

<?
//header('Refresh: 2; URL="register_test.php');
$path = "C:/path to image upload folder/";
//define("C_FILEPATH", "C:/path to image upload folder/");
$max_size = 1048576;
$id = $_GET['id'];
//chmod($path, 0777);

if (!isset($HTTP_POST_FILES['userfile'])) die ("No image selected."); 

if (is_uploaded_file($HTTP_POST_FILES['userfile']['tmp_name'])) {

if ($HTTP_POST_FILES['userfile']['size']>$max_size) { die("The file is too big<br>\n"); }
if (($HTTP_POST_FILES['userfile']['type']=="image/gif") || ($HTTP_POST_FILES['userfile']['type']=="image/pjpeg") || ($HTTP_POST_FILES['userfile']['type']=="image/jpeg")) {

if (file_exists($path . $HTTP_POST_FILES['userfile']['name'])) { die("The file already exists<br>\n");}
$tmp_file = $HTTP_POST_FILES['userfile']['tmp_name'];
$new_file = $path.$HTTP_POST_FILES['userfile']['name'];

$res = copy($tmp_file,$new_file);

if (!isset($res)) { die("Upload Failed!<br>"); }
echo "Upload Sucessful<br>Redirecting back to Your Details.<br>\n";

echo "File Name: ".$path.$HTTP_POST_FILES['userfile']['name']."<br>\n";
echo "File Size: ".$HTTP_POST_FILES['userfile']['size']." bytes<br>\n";
echo "File Type: ".$HTTP_POST_FILES['userfile']['type']."<br>\n";

//Image Magick
$rndnum = rand(10,999999);
exec("C:\\imagemagick\\convert.exe -resize 800 ".$new_file." ".$path.$rndnum.$id."minus_01".".jpg");
exec("C:\\imagemagick\\convert.exe -resize 420 ".$new_file." ".$path.$rndnum.$id."minus_02".".jpg");
exec("C:\\imagemagick\\convert.exe -resize 105 ".$new_file." ".$path.$rndnum.$id."minus_03".".jpg");
exec("C:\\imagemagick\\convert.exe -resize 72 ".$new_file." ".$path.$rndnum.$id."minus_04".".jpg");
$dbsave = $rndnum.$id;
//print "<br>Thumbnail: ".$path."thumb".$rndnum.".jpg";

//deletes original image
unlink($new_file);

//insert images into database
$connection = mysql_connect("server","usernmae","password") or die('Could not connect to the database server'); 
$db = mysql_select_db("database", $connection) or die ("Unable to select database."); 
$sql = "INSERT into images (listing_id,url) values('$id', '$dbsave')";
$sql_result = mysql_query($sql,$connection) or die ("Could not connect to database test"); 
} else { echo "Wrong file type<br>\n"; exit; }
}
?>
<script language="JavaScript">
opener.location.reload();
self.close();
</script>

any help is greatly appreciated.
cheers aron.

you could download imagemagik to your server and leave the code the same...

[aron]

they wont let me.

i'm not sure we're talking the same point here

a virtual server account is on a machine with many other similar accounts, so normally the host installs things like imagemagik or gd somewhere where every account can access it

what you can do is upload the imagemagik files into your account, and call them using exec

this means the host doesn't need to do any work, and your not asking them to provide it to everyone.

i've done this before with imagemagik and exim while installing Gallery

the code is from another site i have done with another provider whos servers are on a windows machine and who has imagemagic installed.

this is on another provider who runs linux machines. for starters wouldnt be able to run .exe off a linux machine (im assuming this) ill see if they have image magic installed (somone told me they didnt)

otherwise the only thin i can do is convert it to gd
