You can also try to see if there's settings in your e-mail under:
Options
Mail Settings
Display Internet Images.
Which should be set to display images automatically.
The names might not be the same for the option and stuff, but it should be something similar to this. Seeing as all the images are showing red x's, the mail application, or web page is not downloading them from the server. I had this happen to me once, and I hope this helps...
