Gallery Inside One Post

These functions will help:

//function to get next or previous keys in an array function array_navigate($array, $key){ $keys = array_keys($array); $index = array_flip($keys); $return = array(); $return['prev'] = (isset($keys[$index[$key]-1])) ? $keys[$index[$key]-1] : end($keys); $return['next'] = (isset($keys[$index[$key]+1])) ? $keys[$index[$key]+1] : current($keys); return $return; } function previous_attachment_ID($att_post){ //get the attachments which share the same post parent $images =& get_children('post_type=attachment&post_mime_type=image&output=ARRAY_N&orderby=menu_order&order=ASC&post_parent='.$att_post->post_parent); if($images){ //get the id of the previous attachment $ppid_arr = array_navigate($images, $att_post->ID); $ppid = $ppid_arr['prev']; return $ppid; } return false; } //previous attachment link function function prev_att_link($att_post=null){ if($att_post == null){ global $post; $att_post = get_post($post); } $ppid = previous_attachment_ID($att_post); if($ppid != false){ return '<a href="' . get_attachment_link($ppid) .

With this you can implement a previous next setup as you wanted, and, you can show all the thumbnails in the gallery.

e.g.:

<div class="back_to_gal_link"> <?php echo back_to_gal_link().'<br />'; ?> </div> <div class="prev_next_links"> <?php if(prev_att_link()){ echo prev_att_link(); } if(prev_att_link() && next_att_link()){ //insert a seperator between the two links echo ' | '; } if(next_att_link()){ echo next_att_link(); } ?> </div> <div class="thumbnails"> <?php echo show_all_thumbs(); ?> </div>
