}示例2: checkMemoryForImage

*
* The code was adapted from http://www.php.net/manual/en/function.imagecreatefromjpeg.php#64155. It will first
* attempt to do it with available memory. If that fails, Craft will bump the memory to amount defined by the
* [phpMaxMemoryLimit](http://buildwithcraft.com/docs/config-settings#phpMaxMemoryLimit) config setting, then try again.
*
* @param string $filePath The path to the image file.
* @param bool $toTheMax If set to true, will set the PHP memory to the config setting phpMaxMemoryLimit.
*
* @return bool
