This displays all images in a control:

<% control CarouselImages %>
<img src="$Image.URL" alt="$Caption.ATT" />
<% end_control %>

But I only want to do a conditional to check if there are more than 3 images:

<% if CarouselImages >3 %>
<h1>There are more than three images!</h1>
<% end_if %>

You cannot do that in the templates. You would need to write a snippet of PHP

function Carousel() {
if($this->CarouselImages()) { if($this->CarouselImages()->TotalItems() > 3) return "Too Many"; }
return $this->CarouselImages();
}
