Make photos to be searchable

Hi

Wondering if there is any way of making the photos to be indexed via wp search function.

I′ve already enable title and tags on flickr but trying to search a photo using the title or tags gives me nothing ??

On my site i′m using also the nextgen gallery and that function is only possible via a little plugin (nggSearch) and adding some code on my theme′s search.php, somethink like that:

<?php get_header(); ?>

<div class="lay1">

<div class="search_term"><h2 class="postsearch"><?php printf( __( 'Resultados da Busca por: %s', 'theron' ), '<span>' . esc_html( get_search_query() ) . '</span>'); ?></h2>

            <a class="search_count"><?php _e('Total de posts encontrado', 'theron'); ?> <?php /* Search Count */ $allsearch = &new WP_Query("s=$s&showposts=-1"); $key = esc_html($s, 1); $count = $allsearch->post_count; _e('', 'theron'); _e('<span class="search-terms">"', 'theron'); echo $key; _e('"</span>', 'theron'); _e(' — ', 'theron'); echo $count . ''; wp_reset_query(); ?></a>

            <?php get_search_form(); ?>

            </div>  

<div class="lay1_wrap">

                   <?php if(have_posts()): ?><?php while(have_posts()): ?><?php the_post(); ?>

                <div <?php post_class(); ?> id="post-<?php the_ID(); ?>">
                <div class="post_image">

                     <!--CALL TO POST IMAGE-->

                    <?php if ( has_post_thumbnail() ) : ?>

                    <div class="imgwrap">

                        <div class="date_meta"><?php the_time('d'); ?><?php the_time('S'); ?> <?php the_time('M'); ?> <?php the_time('Y'); ?></div>

                    <a href="<?php the_permalink();?>"><?php the_post_thumbnail('medium'); ?></a></div>

                    <?php elseif($photo = theron_get_images('numberposts=1', true)): ?>

                    <div class="imgwrap">

                        <div class="date_meta"><?php the_time('d'); ?><?php the_time('S'); ?> <?php the_time('M'); ?> <?php the_time('Y'); ?></div>                      

                	<a href="<?php the_permalink();?>"><?php echo wp_get_attachment_image($photo[0]->ID ,'medium'); ?></a></div>

                    <?php else : ?>                    

                    <div class="imgwrap">

                        <div class="date_meta"><?php the_time('d'); ?><?php the_time('S'); ?> <?php the_time('M'); ?> <?php the_time('Y'); ?></div>                       

                    <a href="<?php the_permalink();?>"><img src="<?php echo get_template_directory_uri(); ?>/images/blank_img.png" alt="<?php the_title_attribute(); ?>" class="thn_thumbnail"/></a></div>                                

                    <?php endif; ?>
                </div>           

                 <div class="post_content">

                    <h2 class="postitle"><a href="<?php the_permalink();?>" title="<?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>

                    <?php theron_excerpt('theron_excerptlength_teaser', 'theron_excerptmore'); ?> 

                </div>               

                        </div>

            <?php endwhile ?> 

            <?php endif ?>

</div>
<div><?php if ( function_exists( 'ngg_images_results' )  && have_images() )  : ?>

        		<h2 class="postitle">Imagens encontradas</h2>
        		<?php ngg_images_results(); ?>
        		</div>
        		<?php endif; ?>   

            <?php if (function_exists("theron_paginate")) {theron_paginate();} ?>

            <div class="hidden_nav"><?php paginate_links(); ?></div>

    </div>             

<?php get_footer(); ?>

I know that ngg uses a completely different approach, the images are present on wp media, but anyway….

Any light on this will be great.
