Question

image_hwstring( int|string $width,  int|string $height )

Retrieve 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.
