When applying a long fade or delay in slideshow mode, a blank background may appear for a short while before the first image fades in. There is an option to set the first image as a CSS fallback to take care of that first bit of time. This filter allows you to set your own.


Changing the image

function rkv_css_default( $image ) {

	$image	= MY_DOMAIN.'/images/my-css-default.jpg';

	return $image;
add_filter( 'backstretch_css_fallback', 'rkv_css_default');
