Image Resize Problem

Ancoats · February 10, 2009

Hi all,

I have a page/form which is a member profile page, where the basic idea is that the user, once logged in, will be able to create a personal member profile, and have the option to select an image they wish to upload... all this works fine (the image selected gets uploaded and moved to the specified folder I have set for it.)

However, I am currently having problems getting the uploaded image to 'resize' to 150 px 150px (ignore the example in this code, I know its set to half the image size... but even this doesnt work) but this doesnt seem to be working... as the original image size is on the server. Been trying to work out where I am going wrong and assume that maybe its something to do with the overall code, not just the actual bit that resizes?

Anyway, any help or pointers would be helpful. (I am not a PHP guru so go easy, lol)

Code is

<?php
//start the session
session_start();

//connect to database
include ('includes/db.php');
?>
