How come the images arent loading properly?

The site’s Adress should be http://www.loftycsei.org/.

You got a Problem in your timthumb.php, it is delivered with your Theme.

It uses a deprecated Function on Line 549, ereg. The Problem is that when your image is processed, it outputs the deprecated warning before sending the Headerinformation for the Contents being a JPG.

You got various methods of fixing this.

I would suggest steering away from using Timthumb due to security issues, and using custom Image sizes for your website, everything can be done using the WordPress built in functions.

Another possible solution would be disabling the deprecated warnings:

in your php.ini

error_reporting  = E_ALL & ~E_DEPRECATED

or while running your scripts:

error_reporting(E_ALL & ~E_DEPRECATED);

You can also run the deprecated function minus the error handling.

But as I already mentioned, I would build the theme NOT based on timthumb.
