I notice that Internet Explorer 8 sometimes block images from showing when Gmail switch over to HTTPS for their webmail accounts. I also had similar problems with my ISP’s Shaw mail. It is an easy problem to fix by just going into Internet Explorer 8’s Internet Security settings.
1. Go to Tools , and Click on Internet Options.
2. Go to security Tab, and click on Custom level button.
3. Under the Miscellaneous find “Display Mixed Content” and set to enable.
Press OK, and press OK on Internet Options. Close IE 8 and restart Internet Explorer 8.
Now you should be able to see pictures inside e-mails again on your HTTPS web e-mail accounts.
