Is there any way to run a script again after an ajax call?

I have a photoswipe (lightbox) jquery plug-in I call like this:

jQuery(document).ready(function($){



    if( $('.img-frame a').length > 0 ){



        var myPhotoSwipe = $(.img-frame a).photoSwipe();



     }

});

I also have an ajax 'load more posts' function, and obviously photoswipe doesn't target images loaded after the first page load.

I don't have much ajax knowledge, any help on this? Thanks

UPDATE: Here's the 'load more' script:

jQuery(document).ready(function($) {



    // The number of the next page to load (/page/x/).

    var pageNum = parseInt(djwd_load_posts.startPage) + 1;



    // The maximum number of pages the current query can return.

    var max = parseInt(djwd_load_posts.maxPages);



    // The link of the next page of posts.

    var nextLink = djwd_load_posts.nextLink;



    /**

     * Replace the traditional navigation with our own,

     * but only if there is at least one page of new posts to load.

     */

    if(pageNum <= max) {

        // Insert the More Posts link.

        $('#content')

            .append('<div class=lp-placeholder-'+ pageNum +'></div>')

            .append('<p id=lp-load-posts class=long-button><a href=#>Load More Posts<i class=icon-chevron-down icon-large></i></a></p>');



        // Remove the traditional navigation.

        $('#nav-below').remove();

    }





    /**

     * Load new posts when the link is clicked.

     */

    $('#lp-load-posts a').click(function() {



        // Are there more posts to load?

        if(pageNum <= max) {



            // Show that we're working.

            $(this).text('Loading posts...');



            $('.lp-placeholder-'+ pageNum).load(nextLink + ' .post',

                function() {



                    $( this ).hide().fadeIn(700);



                    // Update page number and nextLink.

                    pageNum++;

                    nextLink = nextLink.replace(//page/[0-9]?/, '/page/'+ pageNum);



                    // Add a new placeholder, for when user clicks again.

                    $('#lp-load-posts')

                        .before('<div class=lp-placeholder-'+ pageNum +'></div>')



                    // Update the button message.

                    if(pageNum <= max) {

                        $('#lp-load-posts a').text('Load More Posts');

                    } else {

                        $('#lp-load-posts a').text('No more posts to load.');

                    }

                }

            );

        } else {

            $('#lp-load-posts a').append('.');

        }   



        return false;

    });

});

I call it in Wordpress functions.php this way:

 function djwd_ajax_load_init() {

    global $wp_query;



    if( !is_singular() ) {

        wp_enqueue_script('ajax-load-posts', get_template_directory_uri() . '/js/ajax-load-posts.js', array('jquery'), true );



        $max = $wp_query->max_num_pages;

        $paged = ( get_query_var('paged') > 1 ) ? get_query_var('paged') : 1;



        wp_localize_script(

            'ajax-load-posts',

            'djwd_load_posts',

            array(

                'startPage' => $paged,

                'maxPages' => $max,

                'nextLink' => next_posts($max, false)

            )

        );

    }

 }

 add_action('template_redirect', 'djwd_ajax_load_init');
