Why do I get this "Unable to load" error?

[ruzel]

I would like to have the following URL:

http://mysite.com/gallery

Other than config options, this controller does not really need the MY_controller library--just CI_controller.  However, since MY_controller doesn't overwrite the load->view method, I'm using it to keep the config options.  So the gallery function should look like this:

$this->load->view($this->config->item('theme_folder') . 'gallery');

However, this results in 

"Unable to load the requested file: http://www.mysite.com/application/views/themes/mytheme/gallery.php"

That URL is correct and the file is a simple HTML file with "Hello World"  Can anyone tell me why it's not loading?
