Minor fix to prevent a potential undefined variable notice.

(and slight improvement to the regex)

Fixes:
Undefined offset 1 in /path/to/wp-content/plugins/ricg-responsive-images/wp-tevko-responsive-images.php:350

Hmm... is it just me or are you not using the WP Coding Standards ? I looked at why linthub is failing and all I see are things which are in direct contrast to the WPCS.

Good catch @jrfnl. We could probably cut it down even further and do something like:

if ( preg_match( '/ width="([0-9]+)"/', $atts, $width ) &&  preg_match( '/ height="([0-9]+)"/', $atts, $height ) ) {
  $size = array(
    (int) $width[1],
    (int) $height[1]
  );
}

Spaces before the attributes are probably a good idea. And, yes, our Linthub config is acting up right now so you can ignore that check for now (see: #185).

You're welcome ;-)
