Edublogs Homepage: service-block images - not HTTPS / SSL compatible

Looks like the "service-block" section is serving up the absolute URL via HTTP instead of HTTPS. Here's an example:

<div class="service-block">
<a href="/about/"><img src="http://crescentridgehomeowners.com/wp-content/uploads/thumb/edu1_normal.jpg" width="200" height="100" alt="

all 6 of the images are like that.
