Saints,
I just wanted to recommend this hosting solution MaxCDN. What essentially it does is allow parts of your site like images to be hosted on their servers which they have world-wide. So when someone accesses the website from across the world they serve the images from the closest server they have. Hence it speeds up the website loading for users. All of the images on SermonIndex are hosted with them and it helps significantly to speed up the site loading time.
This will work well for ministry blogs, church sites etc. There are some starting points offered here that are "25% off" http://www.maxcdn.com/maxcdncoupon/
It is our goal to run SermonIndex as "in-expensively" as possible but at the same time allowing great growth and access for the ministry to expand on the internet.
