Images are turned off by default as a security enhancement.
By opening an email with images, anyone including spammers, would be able to find out that you have opened the email if you have automatic image loading turned on, scammers may be able to see:
Your location.
Your Internet service provider or mobile company.
Device you used to open the email.
Operating system you’re using.
Email client you’re using.
Web browser you’re using.
and therefore the spammer would know that the email address is active and could of course decide to send more spam to that email address or specifically target you with a scam of some sort.
If you have decided to turn images on be selective with your choice.
