psd files won't display. right click on the red x and check "properties" see where the path to the images is set. Then, you need to install your images there. Custom styles are not always installed the same way, some install in the forum root, some in the forum/images folder. Make sure yours installation is correct. The instructions for the style should have told you were to install them. If you are using a portal and /forums instead of root, you need to check that the paths are set correctly in stylevars and MainCSS.
