This usually happens when the email reader’s image settings are not properly set for viewing an HTML email. One option is to click the 'View online' link displayed in the email. Clicking the link will you’re your active browser so you can view the newsletter with all images displayed.
Additionally, many email applications automatically block images included in 'HTML' emails from downloading for viewing. The intent is to block images that may do harm if downloaded. Each email application has its own way of allowing users to see the images. The following shows how common programs and webmail applications address image viewing:
MS Outlook: right-click one of the blocked images and select the 'download images' option.
GMail: Click on the 'Display images below' option at the top of your email.
Yahoo: Click on the 'Show HTML Graphics' at the bottom of your email.
Thunderbird: Click on the 'Show Images' button that is usually located in the top-right of your email.
Hotmail / MSN / Livemail: Click on 'Show Content' at the top of the email. Alternatively if you click on the 'Mark as safe' link in the 'From' line of the email header, all emails from that email address will be seen as 'safe' in the future. Note that if you don't click 'Show Content' or 'Mark as safe' you won't be able to click on any links either.
