You could put it in a custom library and load it when necessary.

I adjusted and tested a working function from php.net code snippets.

Code:

class Image_util
{
   function img_from_url($imgurl,$downloaddir='',$quality=85)
   {
    $file = substr(strrchr($imgurl,'/'),1);
    $filename = substr($file,0,strrpos($file,'.'));
    $ext = strtolower(substr(strrchr($file,'.'),1));
    if ($ext == 'jpg' || $ext == 'jpeg')
    {
      $img = @imagecreatefromjpeg($imgurl);
    }
    else if ($ext == 'png')
    {
      $img = @imagecreatefrompng($imgurl);
    }
    else if ($ext == 'gif')
    {
      $img = @imagecreatefromgif($imgurl);
    }
    // If an image was successfully loaded, test the image for size
    if ($img)
    {
       imagejpeg($img,$downloaddir.$filename.'.jpg',$quality);
    }
  }
}

Hi Xwero..

I understand you code, But where I have to add this code and How I will call this function.
Did you please explain in detail.

I would use CURL to snatch the image down.

You have to put it in a file called Image_util.php and put it in the application/libraries folder.

in the config/autoload.php file you can add it to the library array if you use it througout your site or if it's only on a few pages you can load the library in the controller where you call the function too

Code:

class Albums extends Controller
{
    function Albums()
    {
       $this->load->library('image_util');
    }

    function add-image()
    {
       if(isset($_POST['url']))
       {
          $this->image_util->img_from_url($_POST['url']);
       }

    }
}

This is example code, the input should be validated.

curl is more robust that is true but i think his question is about how to call functions from custom libraries.
