Using Firefox 126.96.36.199 tried to search with following options:
Search text: mark
Type: any match
but instead of search results page, i've got this message:
"/var/www/openclipart.org/htdocs/cclib/cc-mediahost.php"(639): Undefined index: download_url [2007-08-22 06:09 am][127.0.0.1][/media/search/results]
Closing all openclipart bugs as openclipart is now on launchpad, as per request from Jon Philips.
