I have the following code:

<%= link_to(image_tag(...)) %>

The problem is that Rails sanitizes the images so it gets rendered as:

&lt;img src=... /&gt;

I could use html_safe, but that's painful and makes my code less
readable.

In Rails2 I could declare a whitelist such as:

config.action_view.sanitized_allowed_tags = 'a', 'blockquote', 'img',
...

But it doesn't seem to work anymore. Did I miss anything in the
transition from Rails 2 to 3?
