Ditto and Flexslider

I am working on a Modx Evo site that has a Flexslider for references. Each reference is a document. Now i want to use Ditto to displays 2 documents contents per Flexslider slide.

Any help is welcome. The static version of the site is at yvonneeikens.nl

Thanks.

I need a bit more info.

&limit=`2` will show max 2. &random=`1` will show them random. &startId=`3` will show the items under page with id 3.


Do you mean:
&tpl=`chunk-x`

chunk-x:
<li><img src="[+tv01+]" /></li>
<li><img src="[+tv02+]" /></li>
