Integrating Gallery with a model of your application is very simple and takes only seconds, and the best is you do not need to change your database. To begin open the model you want to attach a gallery, in this example will be Product.php

Class Product extends AppModel{
    public $name = 'Product';
}

Now you just need to add the $actsAs attribute in your model:

Class Product extends AppModel{
	public $name = 'Product';
	public $actsAs = 'Gallery.Gallery';
}

And its done! To list all galleries attached to a Product, you can do something like this:

$this->Product->id = 10;
$this->Product->getGallery();

Every Picture that have Gallery attached at it already have 1 gallery to start uploading files. To link to a Picture gallery is quite simple:
Using the CakePHP Html helper:

echo $this->Html->link('New gallery', array(
		'controller' => 'gallery',
		'action' => 'upload',
		'plugin' => 'gallery',
		'model' => 'product',
		'model_id' => $product_id
		));

If you don't want to use the Html helper you can link to this pattern: /your_app/gallery/upload/{model}/{model_id}

You can create a gallery that don't belongs to any model, a standalone gallery. To create one of those you will use the same example as above, but passing the model and the model_id as NULL:

echo $this->Html->link('New gallery', array(
		'controller' => 'gallery',
		'action' => 'upload',
		'plugin' => 'gallery',
		'model' => null,
		'model_id' => null
		));

All configuration related to images you can find at app/Plugin/Gallery/Config/bootstrap.php

$config = array(
	'App' => array(
		# Choose what theme you want to use:
		# You can find all themes at Gallery/webroot/css/themes
		# Use the first name in the file as a parameter, eg: cosmo.min.css -> cosmo
		'theme' => 'cosmo'
	),
	'File' => array(
		# Max size of a file (in megabytes (MB))
		'max_file_size' => '20',

		# What king pictures the user is allowed to upload?
		'allowed_extensions' => array('jpg','png','jpeg','gif')
	),
	'Pictures' => array(
		# Resize original image. If you dont want to resize it, you should set a empty array, E.G: 'resize_to' => array()
		# Default configuration will resize the image to 1024 pixels height (and unlimited width)
		'resize_to' => array(0, 1024, false),

		# Set to TRUE if you want to convert all png files to JPG (reduce significantly image size)
		'png2jpg' => true,

		# Set the JPG quality on each resize.
		# The recommended value is 85 (85% quality)
		'jpg_quality' => 85,


		# List of additional files generated after upload, like thumbnails, banners, etc
		'styles' => array(
			'small' => array(50, 50, true), # 50x50 Cropped
			'medium' => array(255, 170, true), # 255#170 Cropped
			'large' => array(0, 533, false) # 533 pixels height (and unlimited width)
			)
		)
	);
	Configure::write('GalleryOptions', $config);	

You can create more styles on styles array of modify the default size of the defaults

PS: don't modify the default names as medium or small. This files are used by the plugin.
