Perch Buckets

I believe that I have a slight issue in the way I'm trying to implement Buckets. I changed the config file so now all files are being loaded to a root folder on my server called _fileUploads. That worked out well so no issues here.

Next I was hoping that when a client uploaded images from the CMS it would go into a sub-folder of the _fileUploads directory. So I added the following markup to my template.

<img src="<perch:content type="image" id="image" label="Image" bucket="staffPics"/>" style="width:250px; float:left;" alt="<perch:content type="text" id="staffTitle" alt" label="Staff Title" required="true" />" />

Below is my buckets.php file which is uploaded in the config folder

<?php 
    return array(
        'staffPics' => array(
            'web_path'  => '_fileUploads/staffPics',
            'file_path' => '/home/floridat/public_html/_fileUploads/staffPics'
        ),
        'mainPics' => array(
            'web_path'  => '_fileUploads/mainPics',
            'file_path' => '/home/floridat/public_html/_fileUploads/mainPics'
        ),
        'pdfs' => array(
            'web_path'  => '_fileUploads/pdfs',
            'file_path' => '/home/floridat/public_html/_fileUploads/pdfs'
        ),
        'blogPics' => array(
            'web_path'  => '_fileUploads/blogPics',
            'file_path' => '/home/floridat/public_html/_fileUploads/blogPics'
        )
    );
?>

All file uploads are in the _fileUploads directory but not in a different directory and the system isn't applying the uploaded image into the specified bucket. I'm fairly certain it is user error, but I can't figure it out so I figured I would see if anyone had an answer.
