title: Adding Mouseover Effect to Submit Button (Rails 3)
body: <p>Quick question, I'm trying to add a rollover effect to a submit button, but it doesn't seem to be working. i originally used CSS to create the effect but CSS creates a bit of a flicker when the the image is rolled over (my guess is from loading the rollover image).</p>
  
  <p>Heres the code for the button:</p>
  
  <pre><code>&lt;%= image_submit_tag ("sharebutton_up.jpg"), :mouseover =&gt; ("sharebutton_down.jpg")%&gt;
  </code></pre>
  
  <p>Any ideas on how to fix this code, or a different way to create the rollover effect?</p>
