Fetching Image from other post/page with custom type

Question

I'm building a theme that display image according to a category. Exemple, There a Fashion section, which is a page. On that page I have uploaded photo related to fashion. Another page is Portraits, which display portrait photography and so on. On my home page I would like to display all the recent photo that I have uploaded through the other section/page.

Right now I can only show image related to a specific page or post with this script:

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

 $args = array(
   'post_type' => 'attachment',
   'numberposts' => -1,
   'post_status' => null,
   'post_parent' => $post->ID
  );

  $attachments = get_posts( $args );
     if ( $attachments ) {
        foreach ( $attachments as $attachment ) {
           echo '<li>';
           echo wp_get_attachment_image( $attachment->ID, 'full' );
           echo '<p>';
           echo apply_filters( 'the_title', $attachment->post_title );
           echo '</p></li>';

          }
     }

 endwhile; endif; ?>

How can I extend this script to fetch images/photos in other post/page?

I would like to specified that I'm kind of new in theme developement...

Thanks in advance for your help.

You can achieve that in many ways , but providing that you use a relatively new wordpress, you should use the_post_thumbnail().

you define it in functions.php , like so :

add_theme_support( 'post-thumbnails' ); //thumnails set_post_thumbnail_size( 150,230, true ); // defaultpost thumbnails 
add_image_size( 'your-custom-name-2', 400, 9999 ); // some size thumbnail  
add_image_size( 'your-custom-name-2', 400, 300,false ); // another size 
add_image_size( 'whatEverName', 100, 100, false ); // yet another

The "false" or "true" parameters regard the cropping mode (read more below ) http://codex.wordpress.org/Function_Reference/the_post_thumbnail

and also here

Display thumbnail from custom field

you should then define a post default image when you upload an image (you will see it on the upload screen ) - then you can just call it in your theme like so :

the_post_thumbnail('whatEverName'); //depending on the size you want.

this however , will get you ONE defined image . It will also get you the IMAGE ITSELF . if you want the URL, size or something else, you should use

get_the_post_thumbnail($page->ID, 'whatEverName');

If you want multiple images - you can use this :

<?php //GET THE FIRST IMAGE
    $args = array(
    'order'          => 'ASC',
    'orderby'        => 'menu_order',
    'post_type'      => 'attachment',
    'post_parent'    => $post->ID,
    'post_mime_type' => 'image',
    'post_status'    => null,
    'numberposts'    => 1, //change if you want another number
    );
    $attachments = get_posts($args);
        if ($attachments) {

            foreach ($attachments as $attachment) {

            echo wp_get_attachment_link($attachment->ID, 'thumbnail', false, false);
    }
} ?>

// CONTENT AND OTHER STUFF...

<?php //GET ALL EXPECT FIRST IMAGE
    $args = array(
    'order'          => 'ASC',
    'orderby'        => 'menu_order',
    'post_type'      => 'attachment',
    'post_parent'    => $post->ID,
    'post_mime_type' => 'image',
    'post_status'    => null,
    'numberposts'    => -1,
    );
    $attachments = get_posts($args);
        if ($attachments) {
    $no_show=true;
            foreach ($attachments as $attachment) {
    if($no_show) {$no_show=false; continue; }
            echo wp_get_attachment_link($attachment->ID, 'thumbnail', false, false);
    }
} ?>
