- refactoring of comments.php
- creation of function get_thumbnail_src used everywhere a thumbnail must be displayed - creation of function parse_comment_content (used in comments.php and picture.php) - concerning undefined index on arrays retrieved in database, instead of testing possibly unset values, use of @ operator (smarter...) - add pre tag in default.css stylesheet for debugging purpose (need to have left aligned text) git-svn-id: http://piwigo.org/svn/trunk@579 68402e56-0260-453c-a942-63ccdbb3a9ee
