Theme Problem with Displaying Services Options Images

Every attempt to attach an image to the theme's Services Options screen fails.

The image initially appears on the Service Options screen on the respective service, but disappears after leaving the services page and doesn't display on the site's home page.

Instead, I see the default Blogs MU image displayed. This is despite the fact that I deleted all of these default images from the Media Library.

Help!!!!!!!!!!!

Thanks.

Neil
