bp_get_blog_avatar

WP multisite with buddypress activated global and set via config to run on each blog. No avatar plug in.

Creating a child template. Would like to display the blog avatar in one of my templates. I looked at the file blogs-loop.php and found:

bp_blog_avatar('type=thumb')

The function does not work in my child theme,nor do the other BP functions found in blogs-loop.php. Not sure what I am doing wrong. I am not throwing an error, so I know it is finding the function just fine.
