failed to open stream: No such file or directory

This means it can't find the image. Try doing an echo of $fieldname before getting the image size to make sure you are checking the correct location.

For saftey reasons put session_start(); at the top of the page to avoid the session_Start error.

Can we see the code for the function GetImageSize($param); ??

<?php require_once('Connections/elvisdb.php'); ?>
<?php
session_start(); // Session start should always be before any output.

// make a note of the directory that will recieve the uploaded file 
// full url $uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'uploads/'; 
$uploadsDirectory = 'uploads/'; 

// fieldname used within the file <input> of the HTML form 
$fieldname = 'file'; 

//Resize image
    $imgsize = GetImageSize($fieldname);

    /*== check size  0=width, 1=height ==*/
    if (($imgsize[0] > 250) || ($imgsize[1] > 200)) 
    {
        /*== temp image file -- use "tempnam()" to generate the temp
             file name. This is done so if multiple people access the 
            script at once they won't ruin each other's temp file ==*/
        $tmpimg = tempnam("/tmp", "MKUP");

        /*== RESIZE PROCESS
             1. decompress jpeg image to pnm file (a raw image type) 
             2. scale pnm image

        /*== Step 1: djpeg decompresses jpeg to pnm ==*/
        system("djpeg $fieldname >$tmpimg");

        system("pnmscale -xy 250 200 $tmpimg | cjpeg -smoo 10 -qual 50 >$imgfile");

        /*== remove temp image ==*/
        unlink($tmpimg);
    }

//Upload resized image
$uploadFilename = $uploadsDirectory.$_FILES[$fieldname]['name'];


// now let's move the file to its final location and allocate the new filename to it 
@move_uploaded_file($_FILES[$fieldname]['tmp_name'], $uploadFilename);

$user = $_SESSION['MM_Username'];

$submit=$_POST['submit'];

mysql_select_db($database_elvisdb, $elvisdb);

Thanks. I've put the session_start() at the top.

From what i read online i thought getimagesize was a function. If it isn't then what do i do?

So you are right, do this than:

<?php require_once('Connections/elvisdb.php'); ?>
<?php
session_start(); // Session start should always be before any output.

// make a note of the directory that will recieve the uploaded file 
// full url $uploadsDirectory = $_SERVER['DOCUMENT_ROOT'] . $directory_self . 'uploads/'; 
$uploadsDirectory = 'uploads/'; 

// fieldname used within the file <input> of the HTML form 
$fieldname = 'file';

//Resize image
    $imgsize = GetImageSize($_FILE[$fieldname]['tmp_name']);

    /*== check size  0=width, 1=height ==*/
    if (($imgsize[0] > 250) || ($imgsize[1] > 200)) 
    {
        /*== temp image file -- use "tempnam()" to generate the temp
             file name. This is done so if multiple people access the 
            script at once they won't ruin each other's temp file ==*/
        $tmpimg = tempnam("/tmp", "MKUP");

        /*== RESIZE PROCESS
             1. decompress jpeg image to pnm file (a raw image type) 
             2. scale pnm image
             3. compress pnm file to jpeg image
        ==*/
        
        /*== Step 1: djpeg decompresses jpeg to pnm ==*/
        system("djpeg $fieldname >$tmpimg");
        
        /*== Steps 2&3: scale image using pnmscale and then
             pipe into cjpeg to output jpeg file ==*/
        system("pnmscale -xy 250 200 $tmpimg | cjpeg -smoo 10 -qual 50 >$imgfile");

        /*== remove temp image ==*/
        unlink($tmpimg);
    }

//Upload resized image
$uploadFilename = $uploadsDirectory.$_FILES[$fieldname]['name'];


// now let's move the file to its final location and allocate the new filename to it 
@move_uploaded_file($_FILES[$fieldname]['tmp_name'], $uploadFilename);

$user = $_SESSION['MM_Username'];

$submit=$_POST['submit'];

if(isset($submit)){
mysql_select_db($database_elvisdb, $elvisdb);
$insertSQL = sprintf("INSERT INTO images (imageName, usnm) VALUES ('$uploadFilename', '$user')");

  $Result1 = mysql_query($insertSQL, $elvisdb) or die(mysql_error());
}
echo $uploadfilename

Changed declaration of GetImageSize, see if that works.

    $imgsize = GetImageSize($_FILE[$fieldname]['tmp_name']);

I've changed the code slightly so that it doesn't do the resize until the form is submitted as i thought maybe it couldn't find the file. still no joy

Found this on the getimagesize php page in the user comments http://us2.php.net/manual/en/function.getimagesize.php

getimagesize

I was trying to workaround with the problem of getting the mime type of the image from the raw data (the images data is stored in a database and the mime type is not known in advance). Since getimagesize requires a file name, there are some ways to deal with it:

1. call getimagesize with a URL which points to the image - this is too slow.

2. use PHP file i/o wrapper class.

3. use temporary files. The code for #3 could be as follows:
   function getimagesize_raw($data){
       $cwd = getcwd(); #get current working directory
       $tempfile = tempnam("$cwd/tmp", "temp_image_");#create tempfile and return the path/name (make sure you have created tmp directory under $cwd
       $temphandle = fopen($tempfile, "w");#open for writing
       fwrite($temphandle, $data); #write image to tempfile
       fclose($temphandle);
       $imagesize = getimagesize($tempfile); #get image params from the tempfile
       unlink($tempfile); // this removes the tempfile
       return $imagesize;
}

Maybe that will help.
