In the Display Suite's documentation there's this "Code Snippets" page.
I want to use the code in the section "Limit multiple field" but it doesn't say where to put it. I'm assuming it's supposed to go into template.php of my theme. If that's the case, there might be a mistake in the dcumentation where it says:
Code underneath adds a new formatter for an imagefield which uses a custom function in a
moduletheme called 'imagecache_for_nd_contrib'.
