Hi, I have a small problem with my script. I want to be able to add items with or without an image, and so I have part of my script that runs under this clause:

if (isset ($_FILES['new_image']))
But it doesn't seem to be working as if I try to add an item without an image it is still being run and I am therefore deluged with loads of error code. Is this the right piece of code to use for this. The part of the page that this relates to is:
<form action="<?php echo $_server['php-self'];  ?>" method="post" enctype="multipart/form-data" id="something" class="uniForm">
<input name="new_image" id="new_image" size="30" type="file" class="fileUpload" />
