Is it possible to change image folder in cakephp 2.4 - cakephp

Question

I have read many docs, but failed to solve the problem:
Images in my existing project stored in $_SERVER['DOCUMENT_ROOT'].'/media/'
I want, but can't change in cakephp 2.4 default image folder from $_SERVER['DOCUMENT_ROOT'].'/app/webroot/img/' to any I desire.
lib/Cake/bootstrap.php contains constants:
/**
* Path to the public images directory.
*/
if (!defined('IMAGES')) {
define('IMAGES', WWW_ROOT . 'img' . DS);
}
/**
* Web path to the public images directory.
*/
if (!defined('IMAGES_URL')) {
define('IMAGES_URL', 'img/');
}
and
Configure::write('App.imageBaseUrl', IMAGES_URL);
I tried to change:
IMAGES to $_SERVER['DOCUMENT_ROOT'].'/media/'
IMAGES_URL to /
And it doesn't work at all. All image files still points to $_SERVER['DOCUMENT_ROOT'].'/app/webroot/img/' I see it when try to render image in view:
echo $this->Html->image('/img/ride_scheme/chema.jpg', array( 'width' => 300 ));
If I created in app/webroot/img/ride_scheme image file chema.jpg it rendered, but I changed the folder in IMAGES constant in lib/Cake/bootstrap.php !!!
In documentation I see:
Constants IMAGES_URL, JS_URL, CSS_URL have been deprecated and
replaced with config vari- ables App.imageBaseUrl, App.jsBaseUrl,
App.cssBaseUrl respectively.
Constants IMAGES, JS, CSS have been deprecated.
I gues that is the problem.
Please, show me how to change image folder

According to your description, I reckon IMAGES_URL should be media/ and not just /.
Alternatively, you could add a RewriteRule to your .htaccess (in the project root) to rewrite everything to the media folder (assuming you have an Apache web server with the Rewrite module enabled):
RewriteRule ^app/webroot/img/(.*) /media/$1
Or you could create a symbolic link that links the img/ folder to your media folder (assuming you're on Linux hosting and you have ssh/shell access to your server):
cd app/webroot
rm -rf img/
ln -s ../../media img
