Tiny scrollbar plugin - overview-div wraps despite fixed width

I'm using the Tiny scrol开发者_如何学运维lbar plugin with Jquery to view picture albums. It works fine except for one wrapping issue.

Example: http://67.23.251.125/~emelieze/test/index.php?t=collage&p=collage/Test&scroll=yes

As you probably can see the images (or rather the divs containing the images) is not arranged in a single row, they do so only as you scroll to the right. The overview-div has a fixed width and height, but it still wraps to the viewport-div (the black border makes it obvious.) The width of the overview-div is calculated with php so putting it in the stylesheet is not an option.

The scrollbar-div and it's content looks like this:

<div id='scrollbar2' > 
<div class='viewport' style='height: 330px; '> 
    <div class='overview' style='width: 2560px; height: 330px; '> 

    <div class='scrollimage' style='width: 500px;'> 


   <img src='cms/album/collage/Test/blue.png'> 
   <br> 
  example 3</div>      
    <div class='scrollimage' style='width: 500px;'> 


   <img src='cms/album/collage/Test/green.png'> 
   <br> 
  example 5</div>      
    <div class='scrollimage' style='width: 500px;'> 


   <img src='cms/album/collage/Test/orange.png'> 
   <br> 
  example 1</div>      
    <div class='scrollimage' style='width: 500px;'> 


   <img src='cms/album/collage/Test/red.png'> 
   <br> 
  example 4</div>      
    <div class='scrollimage' style='width: 500px;'> 


   <img src='cms/album/collage/Test/yellow.png'> 
   <br> 
  example 2</div> 

    </div> 
    </div> 

    <div class="scrollbar"><div class="track"><div class="thumb"><div class="end"></div></div></div></div></div></div></div> 

The CSS:

#scrollbar2 { margin: 0px auto 40px auto; clear: both;}  
#scrollbar2 .viewport { overflow: hidden; position: relative; }  
#scrollbar2 .overview { list-style: none; padding: 0; margin: 0; position: absolute; border: 1px solid black; overflow: hidden;}  
#scrollbar2 .scrollbar { position: relative; overflow: hidden;  margin: 0px; clear: both; height: 15px; }  
#scrollbar2 .track { background-color: #EEE; height:4px; position: relative; padding: 0px; }  
#scrollbar2 .thumb { background-color: #CCC; background-position: 100% -15px; height: 4px; cursor: pointer; overflow: hidden; position: absolute; left: 0; top: 0px; }  
#scrollbar2 .thumb .end{ overflow: hidden; background-position: 0 -15px; height: 13px; width: 5px;}  
#scrollbar2 .disable { display: none; }  

.scrollimage {float: left;  border: 0px solid #000; position:relative; margin:0px 10px 0px 0px;}

Inside head-tag:

$(document).ready(function(){var scroll = $('#scrollbar2,.scrollbar,.small_menu,.track,.viewport');
scroll.css('width', (screen.width)/1.5  + 'px')});

$(window).bind('load',function(){

$('#scrollbar2').tinyscrollbar({ axis: 'x'});
});

How can I stop the overview-div from wrapping to the viewport-div?

You should set the overview to the same size as all the divs combined so 5 x 500 = 2500 pixels. The viewport should have a fixed size. it can be dynamic but then you will have to use the tinyscrollbar update method.
