adaptive() without crop

First of all thank you very much for this great module!

Method apaptive() have useful parameter $upscale

public function adaptive($width, $height, $upscale = false)

But I also need resize image without cropping and upscaling.
To achieve this I and once more parameter to make apaptive() more flexible:

public function adaptive($width, $height, $upscale = false, $crop = true)
    {

        if ($this->image) {

            if (!$upscale) {
                if ($width > $this->image["width"])
                    $width = $this->image["width"];

                if ($height > $this->image["height"])
                    $height = $this->image["height"];
            }

            $width = intval($width);
            $height = intval($height);

            $widthProportion = $width / $this->image["width"];
            $heightProportion = $height / $this->image["height"];

            if ($widthProportion > $heightProportion) {
                $newWidth = $width;
                $newHeight = round($newWidth / $this->image["width"] * $this->image["height"]);
            }
            else
            {
                $newHeight = $height;
                $newWidth = round($newHeight / $this->image["height"] * $this->image["width"]);
            }

            if ($crop) {
	            $this->resize($newWidth, $newHeight);
	            return $this->crop($width, $height, "center");            
	        } 
	        else 
	        {
            	return $this->resize($newWidth, $newHeight);
            }


        }
        return false;
    }

Table prefix for storage table

Once more improvement. By default storage table creating in db without tablePrefix. To fix that in iwi/models/Storage.php change:

public function tableName()
	{
		return 'storage';
	}

To:

public function tableName()
	{
		return '{{storage}}';
	}

In iwi/Iwi.php from:

public function verifyTable()
    {
        if (!Yii::app()->getDb()->schema->getTable('storage')) {
            Yii::app()->getDb()->createCommand()->createTable("storage", array(
                'key' => 'string',
                'value' => 'text',
            ));
        }
    }

To:

public function verifyTable()
    {
        if (!Yii::app()->getDb()->schema->getTable('{{storage}}')) {
            Yii::app()->getDb()->createCommand()->createTable("{{storage}}", array(
                'key' => 'string',
                'value' => 'text',
            ));
        }
    }

Fatal Error if image does not exists

When image is not exists Fatal error issued:
Fatal error: Call to a member function cache() on a non-object in \protected\views\model\view.php on line 216

<?php echo Yii::app()->iwi->load("$image->path")->resize(150,100,Image::AUTO)->cache(); ?>

Is any possibility to prevent that, because I work with images catalog that can consist corrupted images?

image type not allowed

Oh! Now I see it, thank you!

But such error is issued if image exists but corrupted, to prevent it I replace throwing CException to return $this:

// Check to make sure the image type is allowed
        if (!isset(Image::$allowed_types[$image_info[2]]))
            return $this; //throw new CException('image type not allowed');
