I would like to create a sidebar on the right of my page. The sidebar's information varies according to the page, so it can have one or many images; text and there is no order in what appears first (text, links or images) and sometime the sidebar doesn't contain any information.

I need help with the following:

• creating the sidebar
  
• creating a new tab to edit the sidebar content under the admin section (tab should be between main and metadata in each page if possibe)
  

I also looked at http://www.ssbits.com/create-a-static-sidebar but it isnt exactly what i wanted.

Thanks guys
