Image seperator in splitted unordered list css

Image seperator in splitted unordered list css

I have an unordered list. Something like
<ul class="dynamic"><br>
<li class="dynamic">"something1"</li><br>
<li class="dynamic">"something2"</li><br>
<li class="dynamic">"something3"</li><br>
<li class="dynamic">"something4"</li><br>
<li class="dynamic">"something5"</li><br>
<li class="dynamic">"something6"</li><br>
</ul>
I have split the list in two columns using css. Now I want to place an
image separator between these two columns.
