I added this line to: /etc/apache2/apache2.conf
AddType application/x-httpd-php .php .php3 .php4 .html
so it treats my html files as php. But now when I add a slash / after any url, the page comes up without any images.. I asked this question and a user gave a suggestion to fix the issue through .htaccess, and it did. But when adding the above line the issue of not showing images comes back.
