[Plugin: Random Image widget] Scaling doesn't work

To fix image scaling change the following lines:

$sidebar ? $img_scale = ' height="150"' : $img_scale = ' height="' . $scale_y . '"';'
and
$sidebar ? $img_scale = ' height="150"' : $img_scale = ' height="' . $scale_x . '"';

To

$scale_y ? $img_scale = ' height="' . $scale_y . '"' : $img_scale = ' height="150"' ;
and
$scale_x ? $img_scale = ' width="' . $scale_x . '"' : $img_scale = ' width="150"' ;
respectively
