Sorry what I meant was, keeping the field as is so its a select field that returns a string of “red” or “white” and then using something like the below to replace “red” with the url of the image
function my_acf_load_value( $value, $post_id, $field ) {
if( is_string($value) ) {
$value = str_replace( ‘Old Company Name’, ‘New Company Name’, $value );
}
return $value;
}
