Sitewide Activity

Is this what you’re after?

.kleo-activity-streams .activity-inner {
    display: none !important;
}

Gotcha. But…. where is the image coming from. From an rtMedia upload with the activity update? From a featured image on a published post activity?

If its from rtMedia upload via an update, you can try

.kleo-activity-streams .rtmedia-activity-text {
    display: none !important;
}

If its from a published post, that would be more difficult since everything is contained within a p tag. There is no separation of text and image. Kleo only stylizes Buddypress output so, you’d have to ask the buddypress guys how to edit their published post activity function so that it doesnt save the text of the post, only the featured image, to the activity table. Or how to change it so it adds a tag around the text and a separate tag around the image so you can control the display of each via css.

Hope that make sense.

It took me forever to figure this out, so I wont be tweaking it for you, but….

Try this code if you want. It doesnt differentiate between the Kleo Activity Stream shortcode and the buddypress activity page. In other words, it will filter all instances of New Post activities. It looks for a featured image for the post. If it finds one, it only returns the featured image. If it doesnt find one, it displays the post excerpt as it normally would.

add_filter( 'bp_get_activity_content_body', 'strip_post_excerpt' );
function strip_post_excerpt( $array  ) {
    global $activities_template;

    if ( 'new_blog_post' == $activities_template->activity->type ) {
        $thumb = get_the_post_thumbnail( $activities_template->activity->secondary_item_id, 'full' );
        if ( $thumb ) {
            $array = $thumb;
        }
    }
    return $array;
}

I hope you find it useful.

It goes in your functions.php file. No css needed.
