/**
* 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.
