In order to create a gallery you will need:

1. First we need to create HTML markup for the gallery. The elements represented here are optional. Each <div> element defines the following gallery parts:

   <div id="loading"></div>
   <div id="slideshow"></div>
   <div id="caption"></div>
   <div id="thumbs">
     ...
   </div>
   

   #controls – adds gallery navigation block;
   #loading – adds a block that displays a spinner image till gallery images are being loaded;
   #slideshow – adds big image block;
   #caption – adds image description block;
   #thumbs – thumbnail images block.
2. Then we build HTML markup for the #thumbs block:

   <div id="thumbs">
     <ul class="thumbs noscript">
       <li>
         <a class="thumb" name="name" href="path/to/slide" title="title">
           <img src="path/to/thumbnail" alt="your image title" />
         </a>
       </li>
       ... (repeat for every image in the gallery)
     </ul>
   </div>
   

3. The link with .thumb class contains the path to the large image. Additionally you can add title and alt parameters.
4. In order to add a gallery item you need to duplicated an existing <li> element (like what you see above).
