Image download problem

[eluser]veledrom[/eluser]
Hi,

I am using this function to download an image that I uploaded before by using Codeigniter. Function successfully downloads it with same name but when I try to open it, I get an error which says "Cannot be opened... file format... is not supported..."

Please help.

Thanks

CONTROLLER:

Code:

public function do_downloadfile()
    {
        $this->load->helper('download');
        // $filepath below produces http://localhost/CI/upload/82df53aae33450324bd26cd880d678b5.png
        $filepath = base_url() . 'upload/' . $this->uri->segment(3);
        $data = file_get_contents($filepath);
        $name = $this->uri->segment(3);
        
        force_download($name, $data);
    }
