Hi Doug,
That was not related to server went down.
When you add a picture into your article, you used something like "../images/aircrafts/small/074/074051.jpg". It looks right in article editor in member section, but won't show up when you view the article from the front end.
It should be "/images/aircrafts/small/074/074051.jpg". URLs or Images used in article should always start with a /.
