Answer 1

Nobody can answer this question.
this is only smallest part of the code, and it can be not the code at all.

To answer the question "why my code is not working" a programmer must learn to debug, and a user must hire a programmer.

IBM has good article to start on debugging: http://www.ibm.com/developerworks/library/os-debug/

Turn all errors on and try to debug some.

Answer 2

what environment you are working in, What I suspect is the path for the image might incorrect

 $config['source_image']    = 'system/application/images/manu.jpg';

try to put full path on it.

 $config['source_image']    = '[path]/system/application/images/manu.jpg';

test it out.
