/**
     * Define real sizes of image from image folder
     *
     * @param string $filename   
     * @return array
     */
    public function getImgRealSizes($filename)
    {
        $path = Mage::getBaseDir('media') . DS . $this->getMediaDir() . DS . $filename;
        if (file_exists($path)) {
            $imageObj = new Varien_Image($path);
            return array('height' => $imageObj->getOriginalHeight(),
                         'width' => $imageObj->getOriginalWidth());
        }

        return FALSE;
    }

/**

* Define real sizes of image from image folder

* @param string $filename

* @return array

public function getImgRealSizes($filename)

{

$path = Mage::getBaseDir('media') . DS . $this->getMediaDir() . DS . $filename;

if (file_exists($path)) {

$imageObj = new Varien_Image($path);

return array('height' => $imageObj->getOriginalHeight(),

'width' => $imageObj->getOriginalWidth());

}

return FALSE;

}

Here: $path = Mage::getBaseDir(‘media’) . DS . $this->getMediaDir() . DS . $filename; – full path to the image file

This function is suitable for such modules as Animated Slider and Splashpage.

Here is an example of its usage:

        public function getMediaDir($filename)
    {
        return ‘myfolder’;
    }

    public function myFunction()
    {
        $filename = ‘mypicture.jpg’;
        $sizes = $this->getImgRealSizes($filename);
        echo $sizes[‘height’] /* display real height of current image */
        echo $sizes[‘width’]  /* display rela width */
        }
