Submitting an image...$_POST['img1'] is not being found

Hi, I've got a PHP script which uses the copy function to upload a submitted image to the server.

The problem I have is that whenever i click submit, I get the following:

No Image Specified.
Notice: Undefined index: img1 in c:\pcanalyst\admin\submit.php on line 62 < - used for testing
