Solved: PHP - photo gallery upload problem

I found this example code of an image gallery that connects to a mysql database. I am trying to use the add a photo portion. I tested the database connection separately and it is fine. For some reason the page just does not trigger the form action. If I change a table field name it does not throw an error. The built in error message also does not display an error. The page refreshes with no errors and no images are uploaded. The only time I see the image is when I select it and then it appears in the image preview section. Any help is appreciated.

<?php include("include.php"); ?>
