i have a friend that will send or forward emails that have images in them but i cannot view them. there will be a small box with red square, a green and a red triangle.  how do i fix this?

It is most likely your friend's problem. If the image is not embedded or attached correctly it won't be displayed in his email.
The small box is a place holder for an image that your email program can not find.

   The other possibility is that you have your email program set up to not display pictures.  If this were the case, other emails also would not show their pictures too unless the picture is embeded in the email.  You can correct this in your email program's settings.
   The reason why an email program would disable the display of pictures (especially those which are links to the internet) is because mass mailed emails often use a picture to track whether you have opened their email or not.
