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';

Notes regarding this preference:
If only the new image name is specified it will be placed in the same folder as the original
If only the path is specified, the new image will be placed in the destination with the same name as the original.
If both the path and image name are specified it will placed in its own destination and given the new name.
