composer correct installation location

[Ali1]

Currently, your package installs as CakephpImaginePlugin in the Plugin directory. I was wondering how another Plugin that corrected itself had done so and found that they added installer-name at the bottom. I know this is a tough one for you as some users may already be using this plugin through composer but here's how your composer should look like:

{
    "name": "burzum/cakephp-imagine-plugin",
    "type": "cakephp-plugin",
    "description": "Imagine Plugin for CakePHP",
    "keywords": ["cakephp","media","image","image-processing"],
    "homepage": "https://github.com/burzum/cakephp-imagine-plugin",
    "license": "MIT",
    "authors": [
        {
            "name": "Florian Krämer",
            "homepage": "http://florian-kraemer.net"
        }
    ],
    "require": {
        "php": ">=5.3.2",
        "imagine/imagine": "*",
        "composer/installers": "*"
    },
    "extra": {
        "installer-name" : "Imagine"
    }
}
