Hello @Invest ,
We don't have any control over whether an email client will allow an image to display. Generally, if images don't display right away in a received email (regardless of source), it's because of security settings on that recipient's end. Check your email system's security settings to make sure images are downloading / allowed to show.
Some email systems, especially for larger businesses/organizations, will never allow images through unless explicitly prompted to by the recipient. for other email systems, especially personal ones, it's a simply matter of clicking to allow that specific email's images, all images from the sending address, or all emails' images in general to be allowed through.
