access to a function in gdlib

Not sure if this is correct usage, but the image manipulation lib seemed to work fine for this:

in controller:
$config['image_library'] = 'gd2';
$this->load->library('image_lib', $config);

in view:
$im = $this->image_lib->image_create_gd($photopath . $pic['picfile'], 2);

// now width is available via imagesx($im)
