Unfortunately, remote images in email messages also come with a privacy risk: the sender knows when you have opened the message. This is not much of a problem with senders you trust, but you do not want spammers and snoopers to know when (or that) you opened a message.
It is best not to download remote images by default. In FastMail, settings this up is easy.
