Galleriffic plugin intergration

Im am using Galleriffic jQuery plugin on a thematic child-theme.

I have reed this post and there is no solution to my problem finding there.

The plugin is working fine but I have to hardcode all the images into the gallery by using my text editor. This is not so user friendly for a client, so I need to find another solution, that is to add the images thruw the administration area. I can imagine a solution using custom fields, but I am not sure how to. Here is the code showing 2 elements(images).

<ul class="thumbs noscript">
  <li>
   <a class="thumb" name="leaf" href="slideshow_image" title="">
     <img src="thumbnail_image" alt="" />
   </a>
  </li>

  <li>
   <a class="thumb" name="leaf" href="slideshow_image" title="">
     <img src="thumbnail_image" alt="" />
   </a>
  </li>
</ul>

Like I mentioned, I see a solution by adding 3 custom fields for each item.

• for a list item
• for a big image or the slideshow image
• for the thumbnail

I hope that I have made myself clear and that you can help me.
