"Hi Larry, \nThank you very much for your reply. I need your further help on the same problem. \n  \nPer your advice, 1)I checked the directory structure in my computer, it's the same layout as Figure 7.5 at page 173 (htdocs/physical_product folder/images folder or products folder.) \n  \n2)i added RewriteBase /physical_product/ in .htaccess file, and index.php in firefox browser looks normal.  \n  \n3) i've tried to change references(from /something to /physical_products/somethingas you suggested) shown below, but the browser reads: Object not found in coffee page:  \n  \n&lt;li&gt;&lt;a href=\"./physical_product/shop/coffee\"&gt;Coffee&lt;/a&gt; &lt;/li&gt; \n  \nWhat else can i try to overcome the structure problem?   \n  \nLook forward to your reply. \n  \nHere is body part of the header.html script in my computer, which i made a little change from your downloadable files. \n  \n  \n&lt;body id=\"page1\"&gt; \n   &lt;!-- header --&gt; \n   &lt;div id=\"header\"&gt; \n      &lt;div class=\"container\"&gt; \n         &lt;div class=\"wrapper\"&gt; \n            &lt;ul class=\"top-links\"&gt; \n               &lt;li&gt;&lt;a href=\"./index.php\" class=\"first\"&gt; &lt;img alt=\"\" src=\"./images/icon-home.gif\" /&gt;&lt;/a&gt;&lt;/li&gt; \n               &lt;li&gt;&lt;a href=\"./cart.php\"&gt;&lt;img alt=\"\" src=\"./images/icon-cart.gif\" /&gt;&lt;/a&gt;&lt;/li&gt; \n              &lt;li&gt;&lt;a href=\"./contact.php\"&gt;&lt;img alt=\"\" src=\"./images/icon-mail.gif\" /&gt;&lt;/a&gt;&lt;/li&gt; \n               &lt;li&gt;&lt;a href=\"./sitemap.php\"&gt;&lt;img alt=\"\" src=\"./images/icon-map.gif\" /&gt;&lt;/a&gt;&lt;/li&gt; \n            &lt;/ul&gt; \n            &lt;div class=\"logo\"&gt; \n               &lt;h1&gt;&lt;a href=\"./index.php\"&gt;Coffee&lt;/a&gt;&lt;span&gt;Wouldn't you love a cup right now?&lt;/span&gt;&lt;/h1&gt; \n            &lt;/div&gt; \n         &lt;/div&gt; \n         &lt;ul class=\"nav\"&gt; \n\t\t\t&lt;!-- MENU --&gt; \n\t\t\t&lt;li&gt;&lt;a href=\"./shop/coffee\"&gt;Coffee&lt;/a&gt; &lt;/li&gt; \n           &lt;li&gt;&lt;a href=\"./shop/goodies\"&gt;Goodies&lt;/a&gt;&lt;/li&gt; \n\t\t\t&lt;li&gt;&lt;a href=\"./shop/sales\"&gt;Sales&lt;/a&gt;&lt;/li&gt; \n\t\t\t&lt;li&gt;&lt;a href=\"./wishlist.php\"&gt;Wish List&lt;/a&gt;&lt;/li&gt; \n\t\t\t&lt;li&gt;&lt;a href=\"./cart.php\"&gt;Cart&lt;/a&gt;&lt;/li&gt; \n\t\t\t&lt;!-- END MENU --&gt; \n         &lt;/ul&gt; \n      &lt;/div&gt; \n   &lt;/div&gt; \n&lt;!-- content --&gt; \n   &lt;div id=\"content\"&gt; \n      &lt;div class=\"container\"&gt; \n         &lt;div class=\"inside\"&gt; \n"
