* Scale down the default size of an image.

*
* The $size parameter accepts either an array or a string. The supported string
* values are 'thumb' or 'thumbnail' for the given thumbnail size or defaults at
* 128 width and 96 height in pixels. Also supported for the string value is
* 'medium' and 'full'. The 'full' isn't actually supported, but any value other
* than the supported will result in the content_width size or 500 if that is
* not set.
*
* Finally, there is a filter named 'editor_max_image_size', that will be called
* on the calculated array for width and height, respectively. The second
* parameter will be the value that was in the $size parameter. The returned
* type for the hook is an array with the width as the first element and the
* height as the second element.
