Copied from the user guide:

Creating a Copy
The resizing function will create a copy of the image file (and preserve the original) if you set a path and/or a new filename using this preference:

Code:

$config['new_image'] = '/path/to/new_image.jpg';

Taken from the user guide:

Creating a Thumbnail

The resizing function will create a thumbnail file (and preserve the original) if you set this preference to TRUE:

$config['create_thumb'] = TRUE;
This single preference determines whether a thumbnail is created or not.

EDIT: Too slow
