<?php

$_SESSION['myusername'];

$connect = mysql_connect("localhost","***","***") or die ("Couldn't connect");

You're evaluating if($_SESSION['myusername']) as a boolean.. I'm not positive what you are trying to do, but don't you need to change that to if(isset($_SESSION['myusername'])) at the top of your page?

ive changed it a little bit so it may be easier to understand, i dont know how to get this to work properly, it is getting an image directory from mysql and the actual image is in ftp.

 

<?php
session_start();

if($_SESSION['myusername']){

$connect = mysql_connect("localhost","","") or die ("Couldn't connect");
mysql_select_db("") or die ("Couldn't find db");

$username = ($_SESSION['myusername']);

$query = mysql_query("SELECT * FROM members WHERE username='$username'");
if (mysql_num_rows($query)==0){
   die;
}else{
   $row = mysql_fetch_assoc($query);
   $location = $row['imagelocation'];
   if($location == ""){
      echo "";
   }else{
      echo "<img src ='$location' width='110' height='110' border='1'><br>";
  echo "Welcome " . ucwords(strtolower($_SESSION['myusername']));
   }
}

}
else
{
echo "<a href='login.php' style='text-decoration:none'><font color=#FFFF00>Sign in </a></font><font color=#FFFFFF><font color=#000000>/</font> Register</font>";
}
?>
