dose this script output th image and html form.

so wont you get something like

all the image output

then a html form

when dont you want to put the image in a file or something then call it from a <img tag

what it does is just upload an image to a file and send information to db... does that fine

i then call image on a different page

this all works fine....

the problem i am having is the fact the image does not get resizied by if(isset($_POST['uploaded'])){

/**

Here i just found this code i tested it and it works with my server

function gdresizetofile($source,$dest,$type,$max_width=420,$max_height=500){
// Get sizes
list($width, $height) = getimagesize($source);
//width
if($width>$max_width){
	$divide=$width/$max_width;
	$newwidth=$width/$divide;
	$newheight=$height/$divide;

	// Load
	$image = imagecreatetruecolor($newwidth, $newheight);
	switch(strtolower($type)){
	case 'jpg':
		$old_image = imagecreatefromjpeg($source);
		break;
	case 'gif':
		$old_image = imagecreatefromgif($source);
		break;
	case 'png':
		$old_image = imagecreatefrompng($source);
		break;
	}
	// Resize
	imagecopyresized($image, $old_image, 0, 0, 0, 0, $newwidth, $newheight, $width, $height);
}else{
	switch($type){
	case 'jpg':
		$image = imagecreatefromjpeg($source);
		break;
	case 'gif':
		$image = imagecreatefromgif($source);
		break;
	case 'png':
		$image = imagecreatefrompng($source);
		break;
	}
}
// Output
imagejpeg($image);

imagejpeg($image);


}

surelly this doesent appear to require a destination but makes no use of it and doesn't return a result?

could i some how change the destination paramater to be passed by reference, then use it in the imagecopyresized call and it will alter the original

ok guys still been messin with it got it a little further but still need help

ok this calls my image

<?php $q = mysql_query($sql) or die("Error running query:".mysql_error());

        					else {

?>

but it wont rename the image to user id ??? $id = $_SESSION['user_id'];

that got through going to require_once '../settings.php'; which then directs you to require ( 'functions.php' ); then in that it has

 function checkLogin ( $levels )
{
	session_start ();
	global $db;
	$kt = split ( ' ', $levels );

	if ( ! $_SESSION['logged_in'] ) {

		$access = FALSE;

		if ( isset ( $_COOKIE['cookie_id'] ) ) {//if we have a cookie

			$query =  'SELECT * FROM ' . DBPREFIX . 'users WHERE ID = ' . $db->qstr ( $_COOKIE['cookie_id'] );

			if ( $db->RecordCount ( $query ) == 1 ) {//only one user can match that query
				$row = $db->getRow ( $query );

				//let's see if we pass the validation, no monkey business
				if ( $_COOKIE['authenticate'] == md5 ( getIP () . $row->Password . $_SERVER['USER_AGENT'] ) ) {
					//we set the sessions so we don't repeat this step over and over again
					$_SESSION['user_id'] = $row->ID;				
					$_SESSION['logged_in'] = TRUE;

					//now we check the level access, we might not have the permission
					if ( in_array ( get_level_access ( $_SESSION['user_id'] ), $kt ) ) {
						//we do?! horray!
						$access = TRUE;
					}
				}
			}
		}
	}
	else {			
		$access = FALSE;

		if ( in_array ( get_level_access ( $_SESSION['user_id'] ), $kt ) ) {
			$access = TRUE;
		}
	}

	if ( $access == FALSE ) {
		header('Location: http://runningprofiles.com/members/index.php');
	}		
}
