No images is usually a configure.php error.
Check if you are defining your root or using the script:
define('DIR_FS_DOCUMENT_ROOT', $DOCUMENT_ROOT);
I use:
define('DIR_FS_DOCUMENT_ROOT', '/home2/webmakr2/public_html'); // where your pages are located on the server. if $DOCUMENT_ROOT doesnt suit you, replace with your local path. (eg, /usr/local/apache/htdocs)

Limited Products Display is only available in SEC. You can look at your categories.php and see if you see any IF statements with LPD_ in the code.
