If you're using Debian, than you have to put your index.html into /var/www but you have to edit your /etc/apache2/sites-available/default and delete the line, which begins with 'RedirectMatch' in the '<Directory /var/www>' block.
If you use Drupal, than you have to manage your pictures with the drupal filemanager and than you can integrate the images into your texts. Or you can copy the images somewhere into /var/www/ (making a subfolder could be useful
) and than you can integrate the images into your texts.
