Is there a recommended way to do this? Currently what I’m doing is this in functions.php

function my_activity_picture_tweak( $content ) {
    $new_content = preg_replace('/<img(.*)>/', '', $content);
    echo $new_content;         
}
add_filter('bp_get_activity_content_body','my_activity_picture_tweak',10,1);

This seems kind of crazy. Is there a better way to do this?
