Since my teens I was interested in the World Wide Web. I started off with CGI scripting - Perl/BASH and moved on to PHP/MySQL based websites like this one. Webnailer was created in 2001-2002 and underwent major reconstructions over the years. I have not updated it recently because its purpose was to be simple to install and support script and not a full-fledged Picture management system. Recently I have made little changes - predominantly compatibility issues submitted by users.
Webnailer's official website is at http://webnailer.sf.net. It has a subproject entry at rousse.pm.org and the latest tarball can be found at the SourceForge site.
