I'd like to center images in postings. I have added a class "centered"to the file default.css, which I then assign to the IMG tag:
margin: 5px auto 0;
<img class="centered" src='http://www.keyscorner.com/wp-content/uploads/2007/11/ledgu5ws60.jpg' alt='LED Lamp' />
But the images remain stubbornly on the left side of the posting. Any suggestions as to what the problem could be?
I have installed an otherwise unmodified version of the template to ensure that I haven't built in a bug when I've made another change to the template.
