Quotation Module doesn't work if site's base path is not "/"

If the base path of your site is not /, then the path to the quotation image is not saved correctly and thus the quotation mark graphics do not show.

For example, if the root of my drupal site is:
www.example.com/my-site/
this module will not work.

To fix, simply prepend base_path() to the saved path. Change line 144 from:
$file = str_replace('(images', '(/' . drupal_get_path('module', 'quotations') . '/images', $file);

to:
$file = str_replace('(images', '(' . base_path() . drupal_get_path('module', 'quotations') . '/images', $file);
