RoR3 - image path error?

I have an image of a comment bubble showing on the index page inside an article p tag which shows how many comments have been added. RoR3 keeps throwing an error and it has me stumped!?

For some reason its looking in the path stylesheets/images/comment.png - when it should only be looking in /images/comment.png as per the Ruby code block. Any suggestions on where I have gone wrong?

_article.html.erb

<div class="article_header">
<b>Article Title: </b> <%= truncate(article.title, :length => 50) %> 

<div class="com-bub">
<img src="/images/comment.png"/>
</div>

<div class="com-cnt">
<%= article.comments.count %>
</div>

The css:

.com-bub {
float:right;
background: url('images/comment.png') no-repeat;
margin: -8px 16px 0px 0px;
}

Error:

your path is incorrect, it should be:

background: url(/images/comment.png) no-repeat;

You need the leading / just like in your markup, also you do not need ticks in your css.

Use a relative link:

background: url(../images/comment.png) no-repeat;

This will take into account scenarios where you deploy to a sub URI (e.g.: www.example.org/myapp/)
