Hi BRoberson1657, couple of suggestions:
Just note this isn't the css file, it's asp - you are coding in the img element, not using css to style it. I don't expect this will be causing the problem, but check the <img> and remove that stray semi-colon:
<img src="sidebar-ad1.png" ; <----
Finally, have you checked the image is in the right directory/folder or that you have provided the correct path in the image src?
