You are done.

OPTIONAL:   If you want to make the slider to appear only on home page follow the next steps:

Give a name for your html/javascript widget. Let's say Slideshow. Go to edit html, expand your template and search for  slideshow. You will find this code or similar (without the red lines):

<b:section class='art-content' id='main' showaddelement='no'>
<b:widget id='HTML2' locked='false' title='Slideshow' type='HTML'>
<b:includable id='main'>
<b:if cond='data:blog.pageType != &quot;static_page&quot;'>
<b:if cond='data:blog.pageType != &quot;item&quot;'>  <!-- only display title if it's non-empty -->
<b:if cond='data:title != &quot;&quot;'>
<h2 class='title'><data:title/></h2>
</b:if>
<div class='widget-content'>
<data:content/>
</div>
<b:include name='quickedit'/>
</b:if></b:if>

For making the slide appear only on home page add the red lines to that code as you see in the upper code.
Save the template. Now you can remove the title of your slider widget.
