The front page is using a page but with the “Full width page template” and named the page as “Welcome to Preference”
Then the menu link for it, I just renamed the label for it as “Home”
The widgets with images (the 4 widgets) are in widget positions Bottom 1, 2, 3, and 4, using the text widget. I am also using a plugin called Dynamic Widgets so that I can control where these widgets are shown (on selected pages). The txt file attached has a sample code for the first widget on the demo site for your reference.
The same as the bottom widgets, I did the same for the footer widgets, published to the footer positions 1, 2, 3, and 4.
**For the front page demo widgets using the images, here is a sample of the demo first widget:
<p><img src="path-to-image.jpg" width="265" height="180" alt="gallery1tn" class="imageborder" style="display: block; margin-left: auto; margin-right: auto;" /></p><p>Yes, the Preference theme was designed and built on WordPress 3.5 to take advantage of the newest and greatest features that comes with it. Plus, you can use popular plugins as well!</p>
