Why doesn't this image_tag work?

I'm trying to get this to work. 

<%= image_tag('http://img.youtube.com/vi/<%= @video_tag %>/hqdefault.jpg') %>

It works with just the link itself but the image_tag to display it is causing the following error:

Error:

   <%= image_tag('http://img.youtube.com/vi/<%= @video_tag %>/hqdefault.jpg') %>


    <div class="videos">

You cannot nest the <% tags. Assuming @video_tag is a string, you can do the following to achieve what you want:

<%= image_tag("http://img.youtube.com/vi/#{@video_tag}/hqdefault.jpg") %>
