This is how I've done it:

Create a new config key to the class where you're calling
getimagesize(). Something like 'image_path'.

Then in your config file you can set it relative to the image path.

$config['Vendor_Class']['image_path'] = dirname(dirname(__FILE__)) . '/images';

Then just call getimagesize($this->_config['image_path'] . '/' . $image);

In my case the class is a view helper which needs to check if an image exists.

Hope that helps.
