1. This is another good place to start: http://codex.wordpress.org/Writing_a_Plugin

   This code should get you going :

   yourPlugin.php
   
   <?php
   /*
   Plugin Name: Name Of The Plugin
   Plugin URI: http://URI_Of_Page_Describing_Plugin_and_Updates
   Description: A brief description of the Plugin.
   Version: The Plugin's Version Number, e.g.: 1.0
   Author: Name Of The Plugin Author
   Author URI: http://URI_Of_The_Plugin_Author
   License: A "Slug" license name e.g. GPL2
   */

   */
   
   $object = new YourPlugin();
   
   //add a hook into the admin header to check if the user has agreed to the terms and conditions.
   add_action('admin_head',  array($object, 'adminHeader'));
   
   //add footer code
   add_action( 'admin_footer',  array($object, 'adminFooter'));
   
   // Hook for adding admin menus
   add_action('admin_menu',  array($object, 'addMenu'));
   
   //This will create [yourshortcode] shortcode
   add_shortcode('yourshortcode', array($object, 'shortcode'));
   
   class YourPlugin{
   
       /**
        * This will create a menu item under the option menu
        * @see http://codex.wordpress.org/Function_Reference/add_options_page
        */
       public function addMenu(){
           add_options_page('Your Plugin Options', 'Your Plugin', 'manage_options', 'my-unique-identifier', array($this, 'optionPage'));
       }
   
       /**
        * This is where you add all the html and php for your option page
        * @see http://codex.wordpress.org/Function_Reference/add_options_page
        */
       public function optionPage(){
           echo "add your option page html here or include another php file";
       }
   
       /**
        * this is where you add the code that will be returned wherever you put your shortcode
        * @see http://codex.wordpress.org/Shortcode_API
        */
       public function shortcode(){
           return "add your image and html here...";
       }
   }
   ?>
   

   Add this code to a yourPlugin.php file and place it in your plugin directory. E.g plugins/yourPlugin/yourPlugin.php

2. Adding something like the following to your plugin should get you started

   /*****Options Page Initialization*****/
   // if an admin is loading the admin menu then call the admin actions function
   if(is_admin()) add_action('admin_menu', 'my_options');
   // actions to perform when the admin menu is loaded
   function my_options(){add_options_page("My Options", "My Options", "edit_pages", "my-options", "my_admin");}
   // function called when "My Options" is selected from the admin menu
   function my_admin(){include('admin-options.php');}
   

   Then you would create a file named admin-options.php with the admin page presentation and functionality. Try a “Hello World” in that file just to see it appear.

   This code is explained in great detail in the WordPress Codex http://codex.wordpress.org/Adding_Administration_Menus which will also give you some examples of how to properly build out your page in a standard way.
