Answer 1

You can use OR (and group your condition)

SELECT   date(datetime) as dateonly ,
sum(CASE message when 'Accepted Images' then 1 else 0 end) as AcceptedIMG,
sum(CASE message when 'Rejected Images' then 1 else 0 end) as RejectedIMG,
sum(CASE when message like '%Changed  to %'    then 1 else 0 end) as ChangeIMG
FROM customer_1.audit_trail 
WHERE  (message  like ('%Changed  to %') OR message in ('Accepted Images','Rejected Images')) 
GROUP BY (dateonly)
ORDER BY (dateonly) asc ;
