Processing an image before the form submits

[eluser]NateL[/eluser]
Thanks Ajren,

My logs folder is set up to 777 (read & write)

inside my controller: product.php

Code:

class Product extends Controller
{

  function addImage()
    {
      log_message('info', 'testing to see if addImage() executes');
    }
}

Ran that script, and nothing has appeared in my logs folder.
