Install

in config/main.php:

    Yii::setPathOfAlias('fileProcessor', '/path/to/extension/');

example for standard yii structure when this module located in extension dir:

    Yii::setPathOfAlias('fileProcessor', dirname(__FILE__) . DIRECTORY_SEPARATOR . '..' . DIRECTORY_SEPARATOR . 'extensions' . DIRECTORY_SEPARATOR . 'yii-file-processor' . DIRECTORY_SEPARATOR . 'fileProcessor');

application config:

    ...
    'controllerMap' => array(
        'image' => array(
            'class' => '\fileProcessor\controllers\ImageController',
        ),
    ),
    ...

if you merge main config with console config, you need unset controllerMap key

modules section:

    'file-processor' => array(
        'baseDir' => realpath(
                __DIR__ . DIRECTORY_SEPARATOR . '..' . DIRECTORY_SEPARATOR . 'www'
            ) . DIRECTORY_SEPARATOR,
        'imageSections' => array(
            'admin' => array(
                'default' => array(
                    'width' => 100,
                    'height' => 100,
                    'quality' => 100,
                    'do' => 'resize', // resize|adaptiveResize
                ),
            ),
        ),
        'imageHandler' => array(
            'driver' => '\fileProcessor\extensions\imageHandler\drivers\MDriverGD',
            // '\fileProcessor\extensions\imageHandler\drivers\MDriverImageMagic'
        ),
    ),

component section:

    'urlManager'=>array(
        ...
        'rules'=>array(

            array(
                'class' => '\fileProcessor\components\YiiFileProcessorUrlRule',
                'connectionId' => 'db',
                'cacheId' => 'cache',
                'controllerId' => 'image',
            ),
            // controllerId - name of the controller, which you set in controller map
            ...
        ),
    ),

add behavior to the model:

    'fileBehavior' => array(
        'class' => '\fileProcessor\components\FileUploadBehavior',
        'attributeName' => 'file_id',
        'fileTypes' => 'png, gif, jpeg, jpg',
    ),
