This is what you're saying, "Search using CSS selector 'imagen' for all
<imagen> tags and invoke 'hide' on each." This tag does not exist in
your DOM.
I assume what you want is to find the element with id='imagen' and hide
it. That would be:
$('imagen').hide();

Move your JavaScript outside of your page. This technique is designed to
be unobtrusive, then your jamming it right back into your page making
obtrusive again.
Start by putting your script code in the JavaScript file that Rails
provides you by default (public/javascripts/application.js). And make
sure you include the default script files in your <head> section:
<head>
...
<%= javascript_include_tag :defaults %>
...
</head>
This one line will include the necessary Prototype JavaScript files, and
also include public/javascripts/application.js for you.
