After installing Windows XP Service Pack 2 (SP2) and downloading emails into Outlook Express, you will find that no images are downloaded with the email. Only the placeholders are shown. This is a security feature that can prevent the person sending the email (usually a company) from knowing that you have opened the mail. To change this option so that images are downloaded with all your mail do the following.
1/ Launch Outlook Express.
2/ On the main Toolbar click the Tools option.
3/ From the drop down menu that appears click Options.
4/ The Options Window will now open.
5/ Click the Security tab.
6/ On the Security tab screen look for the section marked 'Download images'.
7/ Now uncheck the 'Block images and other external content in HTML email'.
8/ Finally click Apply followed by OK to exit.
9/ The next time you download your email the images should all be in place.
