I seem to have resolved this permissions issue by running PHP as a CGI application and adding a quick function to check if a directory already exists or not. I think the system was failing because some directories existed. This is how I changed the controller code for anyone interested and it now works...
Code:
//check if image exists in directory with same string (unlikely but better safe than sorry!)
if (file_exists($set_image_path.$string.'.jpeg')) {$string .= substr($this->session->userdata('username'), 0, 4);}
//check first if directory exists
if (is_dir($set_image_path) == false)
{
mkdir($set_image_path, 0755, true);
//echo 'created a new directory';
}
//echo 'nothing created';
//exit();
$config['upload_path'] = $set_image_path;
$config['allowed_types'] = 'gif|jpg|jpeg|png';
$config['max_size'] = '4000';
$config['max_width'] = '6000';
$config['max_height'] = '4000';
$config['file_name'] = $string.'.jpeg';
$this->load->library('upload', $config);
