Hi,

Thanks for your help but I still don't get it..

I have looked at the RenderViewHelper (DebugViewHelper doesn't seem to 
exist in the current api or at least I can't find it).

I want to display a random image so in good old PHP it would be 
something like:

$nr = rand(0,10);
$img[$nr];

settings.icons contains an array with images.

The ViewHelper I created works and I can output the content in the 
template like this:
<f:render partial="Cases/Images" arguments="{images:randomnr}" />

But how do I render settings.icons.[number generated by ViewHelper]?
