# checkMemoryForImage()
Determines if there is enough memory to process this image.
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 config3:phpMaxMemoryLimit (opens new window) config setting, then try again.
