I just tried the code below and the “first” parameter doesn't work:

{{ images first }}
   <img src="{{ value }}"/>
{ /images }}

In other words, all images were output, not only the first.

To make it work, I had to change it to the code below:

{{ images limit="1" }}
   <img src="{{ value }}"/>
{ /images }}
