Debug osCommerce shop

This project is better take by ppl who can read Chinese language. In the shop [login to view URL] I would like to debug the following: 1. Product category limitation Product Categories has more than 20 categories actually. But somehow after plug-in a template, the box can only show 20 categories only. All extra categories simple disappear. Then user put extra categories to inner level, you can expand the 1st category **specials**, then you can see the sub items underneath; but the top level last item is gone (other pet utilities). 2. Category images In the 2nd level category (sub folders) the user actually has uploaded category photos. But in the shop it doesn't show up. [login to view URL]
