How to change the credit link in the Infinite Scroll footer

If you’d like to change the default credit link appearing in the Infinite Scroll footer, you can use the infinite_scroll_credit filter, like so:

function tweakjp_cust_credit() {
	return '<a href="http://example.com">My Custom Link</a>';
}
add_filter( 'infinite_scroll_credit', 'tweakjp_cust_credit' );

Once you add that code to your theme’s functions.php, a new link will appear instead of the default “Powered by WordPress” link.
