If you want all images except your header image to use the properties that you specified, just put what you have in the CSS file and specify a separate class or ID for the header, like:
<img src="myheaderimage.jpg" id="header" />
Then create a separate entry in your CSS file that targets the header image like:
img#header {
border: none;
padding: none;
}
or whatever styles you want to apply to the header image.
Can you provide a link to your site? It’s probably a simple CSS change, but it’s hard to tell without being able to look at it.
Chances are that they forgot to wrap the li elements in a ul, or the ul is generated by a conditional statement that’s not met. Can you post the code from your sidebar file?
You might want to post a link to your site so people can look at it. It will be easier to troubleshoot this way.
