Despite TCP being reliable, it's fairly easy to corrupt a graphic download when using HTTP Resume. It is also useful when the modification time changes, but the contents doesn't. (It's also somewhat useful for finding duplicate media.) It can't hurt to have, the client isn't forced to check the checksum.
