title: Rails 3 correct image_tag conversion
body: <p>I'm trying to convert parallax effect code to run on a Rails 3 app. I can't get it to run so I'm wondering if I've converted this code properly. The first line in each group is the original code. The second line in each group is my conversion. Can anyone tell me if this is right?</p>
  
  <pre><code>&lt;article class="slide" id="showcasing" style="background:   url('backgrounds/landscape.png') repeat-x top center;"&gt;
  &lt;%= image_tag("backgrounds/landscape.png", :class =&gt; "slide", :id =&gt; "showcasing", :style =&gt; "background: repeat-x top center") %&gt;
  
  &lt;img class="asset left-30 sp600 t120 z1" src="slides/scene1/macbook.png" /&gt;
  &lt;%= image_tag("slides/scene1/macbook.png", :class =&gt; "asset: left-30 sp600 t120 z1") %&gt;
  
  &lt;article class="slide" id="ideas" style="background: url('backgrounds/aqua.jpg') repeat-x top center;"&gt;
  &lt;%= image_tag("backgrounds/aqua.jpg", :class =&gt; "slide", :id =&gt; "ideas", :style =&gt; "background: url('backgrounds/aqua.jpg') repeat-x top center") %&gt;
  
  &lt;img class="asset left-480 sp600 t260 z1" src="img/slides/scene2/left.png" /&gt;
  &lt;%= image_tag("slides/scene2/left.png", :class =&gt; "asset left-480 sp600 t260 z1") %&gt;
  
  &lt;img class="asset left-210 sp600 t213 z2" src="img/slides/scene2/middle.png" /&gt;
  &lt;%= image_tag("slides/scene2/middle.png", :class =&gt; "asset left-210 sp600 t213 z2") %&gt;
  
  &lt;img class="asset left60 sp600 t260 z1" src="img/slides/scene2/right.png" /&gt;
  &lt;%= image_tag("slides/scene2/right.png", :class =&gt; "asset left60 sp600 t260 z1") %&gt;
