Toolbar images missing on new install

I just installed the latest version of FCKEditor on my server. The editor appears to work fine. I'm hoping someone can help me with one small issue. My images in the toolbar are not showing up. I can click on the box where it should be and the functions work fine. I looked in the JS files and the zip to try and figure out where they were. Can anyone help point me to the issue? Thanks!
