 /**
  * Gets an image by id sized and rotated based on the passed params. If the file
  * doesn't exist, it is created using the imager class and stored in cache dir. Every 
  * call after that will load the file directly.
  *
  * When sizing an image with the same width and height, it will be scaled down to the closest
  * width/height and then cropped.
  *
  * To size an image to a specific width, set the width value needed and the height value to 0. 
  * This ensures the specified width is met, and the height is adjusted proportionally. The same
  * can be done by setting the height needed and the width to 0.
  *
  * @param $id int The id of image to get
  * @param $rotation int The degrees to rotate the image, can be null
  * @param $widthOrPercent int When by itself, represents percent to increase/decrease size.
  *      When used with the height param, represents the image width.
  * @param $height int The height to size the image.
  *
  * @return string The relative path from ROOT to the file, if it exists. Boolean false otherwise.
