vBulletin Options, Variables

[ImagenSkins]

Hello, I am trying to create a feature on my website that enables us to showcase content. The content boxes contain a basic header and a caption for the background image. What I want to do with is to add an option inside vBulletin Options or create a new block on the left of admincp/modcp that would allow my mods or other admins to change the image URL and the redirect URL easily without having to go inside style/templates and mess with the code.

This is what we have at FORUMHOME:

<div class="bg-right">
          <div class="featuretitle">
               <a href="{vb:raw link2}">Featured Title 2</a>         
          </div>
           <div class="featurecaption">
               <a href="{vb:raw link2}">{vb:raw caption2}</a>
          </div>
</div>

<div class="bg-left">
          <div class="featuretitle">
               <a href="{vb:raw link1}">Featured Title 1</a>
          </div>
          <div class="featurecaption">
               <a href="{vb:raw link1}">{vb:raw caption1}</a>
          </div>
</div>

This is what we have in the CSS Stylesheet:

.bg-right {
      float: right;  
      background:#303030 url({vb:raw img2});
      height:200px;
      width:400px;      
      margin-right: 50px;
      margin-top: 25px;
      margin-top: 20px;
      position: relative;
      border: 1px outset #aaa;
}   

.bg-left {
      float: left;  
      background: #303030 url({vb:raw img1});
      height:200px;
      width:400px;   
      margin-left: 50px;      
      margin-top: 20px;
      margin-bottom: 25px;
      position: relative;
      border: 1px outset #aaa;
}   

.featuretitle {
      background: #01B1F1 url(/images/titlebg.png) repeat-x;
      padding: 0px 0px 0px 20px;
} 

.featuretitle a{
      color: #FFF;
      font-weight: bold;
      font-size: 14px;
} 

.featurecaption {
      background: #000;
      opacity:0.4;  
      position: absolute; 
      bottom: 0;
      width: 400px;
      height: 20px;
} 

.featurecaption a{
      color: #FFF;
      font-weight: bold;
      font-size: 14px;      
}

How do I create these variables and allow for an input from users in admin/mod cp?

Thanks In Advance,
