Use curl?

Using Phil's Curl library as an example:

Code:

$this->load->library('curl');
$this->load->helper('file');

$img = $this->curl->simple_get("http://img149.imageshack.us/img149/4185/stickynotes.png");

if ( ! write_file("./public/stickynotes.png", $img))
{
  echo 'unable to write the file';
}
