        <label for="Fname">First Name:</label> <input type="text" id="Fname" class="text" value="<?php echo $firstname; ?>" name="Fname" /> <br /><br />
        <label for="Lname">Last Name:</label> <input type="text" id="Lname" class="text" value="<?php echo $lastname; ?>" name="Lname" /><br /> <br />

<?php 
if ($_SESSION["type"]=="T")

        <label>Profile Image:</label> <input type="file" name="image" value="" /><br /> <br />
        <label>Qualification:</label><textarea name="qualification" class="text" id="qualification"><?php echo $qualification;?></textarea><br /><br />

<?php
}
?>
        <input type="submit" class="mybutton" value="Update Profile" />

    </form>

this is my update-profile-action.php

<?php include("../includes/config.php");?>
<?php
$Fname=$_POST["Fname"];
$Lname=$_POST["Lname"];
$image=$_POST["profileimg"];
$briefintro=$_POST["briefintro"];
$qualification=$_POST["qualification"];

$con=mysql_connect($dbserver,$dbusername,$dbpassword);
if (!$con) { die('Could not connect: ' . mysql_error()); }


 mysql_select_db($dbname, $con);
$query=("UPDATE accounts SET firstname='".$Fname."' , lastname='".$Lname."' ,  profileimg='".$image."' ,  briefintro='".$briefintro."',  qualification='".$qualification."' WHERE id=".$_SESSION['id']);
$result = mysql_query($query);
header("Location: update-profile.php?status=3");
mysql_close($con);
?>

i copied only the related data from update-profile.php to making it more easy to read :)
any kind of help will be appreciated :)

Well for starters in update-profile-action.php you refer to $_POST["profileimg"], but the field in update-profile.php has name="image"
Next, you don't access the image file with $_POST, you use $_FILES and associated indexes/functions. And you don't actually store the image in the database, you just store the path (or just the filename) in the DB. Then your code elsewhere uses this file name to access the file.

Do a quick Google search on file upload / image upload forms in PHP, should give you some decent tutorials.

I don't think it's best to store the image in the database. Plus you can search this topic in Daniweb.

Where is your profileimg = '$image' from your input:

<label>Profile Image:</label> <input type="file" name="image" value="" /><br /> <br />

Instead of this:

$query=("UPDATE accounts SET firstname='".$Fname."' , lastname='".$Lname."' , profileimg='".$image."' , briefintro='".$briefintro."', qualification='".$qualification."' WHERE id=".$_SESSION['id']);

Try this:

$query = ("UPDATE accounts SET firstname = '$Fname', lastname = '$Lname', profileimg = '$image', briefintro = '$briefintro', qualification = '$qualification', WHERE id = '$id'");
