It would be best to make up a test page (with CSS included in <style> tags in the head) and post the code here so that we can see what's going on, as otherwise there's no way of knowing what's happening.

Not sure what you mean by that, but no doubt the example code would make that clear.
We really need to see the HTML that goes with that. Also make sure to try Ryan's code above. It may well be that some default margin or padding is causing a problem, and his code is a nice way of putting that to the test.
Never-mind.. Problem finally solved. It wasn't actually a css issue. Those images were just larger than what my css said for the width, so they were displaying off center. Thanks for the help, and sorry for the vague question.
