Https not loading images

I am new to ssl but recently recieved a SSL Certificate for my site(today) but i have two problems

1: I have a login page with am image and when i use the https://site.com/login.php the images dont load. The images are loaded from a folder.

2: How do you get php to be parsed in none .php pages. For example when using https://site.com/page.htm.

I have added
AddType application/x-httpd-php .html .htm
to the .htaccess page but that only works for the standard http:// pages.

Thanks for any help
