Hi Jill,
Please use the following code

// disable the custom profile background generated css.
add_filter( 'bppg_iwilldo_it_myself', '__return_true' );//do not generate css for us

//Our own css
function buddydev_custom_inject_css() {
	if ( ! function_exists( 'bppg_get_image' ) ) {
		return ;// no trouble when the plugin is disabled
	}

	$image_url = bppg_get_image();

	if ( empty( $image_url ) ) {
		return;
	}

	$repeat_type = bp_get_user_meta( bp_displayed_user_id(), 'profile_bg_repeat', true );

	if ( ! $repeat_type ) {
		$repeat_type = 'repeat';
	}
	?>
	<style type="text/css">
		body.is-user-profile #buddypress div#item-body{
			background: url(<?php echo $image_url; ?>);
			background-repeat: <?php echo $repeat_type; ?>;
		}

	</style>
	<?php
}
add_action( 'wp_head', 'buddydev_custom_inject_css', 200 );

You may experiemnet with the css selector to aplly the image to various other parts.

You are welcome. Please do let me know how it goes.

About the MediaPress, I haven’t released an update on wp.org as I am trying to include 2 more developer oriented features in this release. I will need 2 more days.

Thank you.
functions.php is the correct place for it.

Hi Jill,
Sure.

changing this

if ( ! function_exists( 'bppg_get_image' ) ) {
		return ;// no trouble when the plugin is disabled
}

to this

    if ( ! bp_is_user_activity() || ! function_exists( 'bppg_get_image' ) ) {
	    return ;// don't do anything on non activity page.
    }

Will do it.

Best regards
Brajesh
