image_hwstring( int|string $width, int|string $height ): string
Retrieves width and height attributes using given width and height values.
Description
Both attributes are required in the sense that both parameters must have a value, but are optional in that if you set them to false or null, then they will not be added to the returned string.
You can set the value using a string, but it will only take numeric values.
If you wish to put ‘px’ after the numbers, then it will be stripped out of the return.
