You might give a bit more of your configuration in your question. What have you done thus far? Your repeater webpart HTML should look like so:
// HTML content before
<div class="carousel">
// repeater transformation
<div class="item">
<img src='<%# Eval("ImageUrl") %>' alt='<%# Eval("DocumentName")' />
</div>
// HTML content after
</div>
<div class=carousel-pager">
<a class="pager-left"><</a>
<a class="pager-right">></a>
</div>
Don't forget to include your jquery references.
