<p><a href="https://github.com/tomhughes" class="user-mention">@tomhughes</a> the reason I used that is because of the following that I read from the Rails API:</p>

<blockquote>
<p>If you have images as application resources this method may conflict with their named routes. The alias path_to_image is provided to avoid that. Rails uses the alias internally, and plugin authors are encouraged to do so. - <a href="http://api.rubyonrails.org/classes/ActionView/Helpers/AssetUrlHelper.html#method-i-image_path">RubyAPI</a></p>
</blockquote>

<p>I can change it for sure if that is the standard for the code.</p>
