I don’t know if this is the “correct” way to do it but what I did is created a new function file (say avatar_fix.php) and I placed it in the mu-plugins folder so it will be active for all sites.

Then I put inside the avatar_fix.php file the following code with the appropriate <?php and ?> open and close tags (sorry can’t seem to put those into the code tags as it keeps on blanking my code out:
`
function avatar_setup() {
//define(‘BP_AVATAR_UPLOAD_PATH’, ‘/martialarts/wp-content/uploads’);
define(‘BP_AVATAR_URL’, get_bloginfo(‘url’) . ‘/wp-content/uploads’);
}

add_action(‘init’,’avatar_setup’);
`

The reason the issue was happening for me (and I suspect you as well) is that when it went off the main site, the url it was getting for the image was incorrect (was losing the “wp-content/uploads” portion). You may need to adjust the url part if that is not where you’re storing the avatar images.
