Hello @RickD6086 ,
By default our images will try to display unless explicitly blocked by the email program on the receiving end. Depending on the email program, this is either a personal, organization network, or default setting for their email program. Your contacts can try checking their email program's settings to see if there's an option let images automatically display / download. Beyond that, self-authenticating if you have your own domain, having the contacts safelist our domains in their network, and safelist your email address in their email program may aid in the images automatically displaying.
