Yep....haven't a clue. Tried fifteen different images just to see if they would work and they do not.....
This one is what I have had up, and it works fine
<img src="http://www.stoutstandards.com/images/Stoutstandards3.jpg" width="800" height="600">
When I substitute any jpg photo in place of Stoutstandards3...nothing! I checked image Stout89.jpg and can't find an error.
