Several factors can affect your images not displaying in your email.
Make sure you are using absolute URLs. Relative URLs are the equivalent of saying "down the road, left-hand side, walk on for a few houses, you can't miss it." when someone asks you for an address. Absolute URLs are the equivalent of saying "31 Emily Street, Chicago, Illinois, USA, North America, Planet Earth" instead. In order for everyone to be able to see your email's images you need to use the absolute URL (and the images have to be stored somewhere online that is accessible to everyone, too).
Background images don't show up on certain email clients: Always use a solid background color as a backup.
Opens are calculated when images are displayed. If images aren't displayed, your statistics will be inaccurate.
