I got a theme that has lightbox built in, but only for galleries and featured images, not single images.

It just needs to have class="lightbox" added to the images source. I'd like a simple function that will include this automatically.

Not sure why the author left this out.

One way you can accomplish it is this way:


add_action( 'wp_enqueue_scripts', 'your_lightbox_callback' );
function your_lightbox_callback(){

    if( is_single() /* or whatever here */ ) {
        wp_register_script( 'your-lightbox', get_bloginfo( 'template_url' ) . '/lightbox-class.js' );
        wp_enqueue_script( 'your-lightbox' );



var $j = jQuery.noConflict();
$j( document ).ready( function() {

    $j( '#whereveryourpostsare img' ).addClass( 'lightbox' );

} );

Let me add that this hasn't been tested, just typed here on the fly. If you try it do tell me if you have any issues, thanks!
