Hello @LarryH765,
Thank you for reaching out to the Community! This is normal for most email clients for all newsletters with pictures being sent from Constant Contact or not. In your Client's settings, you should have an option to select "Always Display Images" so that they can come through every time without downloading. I do apologize this wasn't an issue we could have fixed on Constant Contact's end. All of your customer's will have to complete this task in order for images to appear every time without choosing to download them.
