LogBlock WebStats uses a method of displaying user skins next to their stats.

This optional feature would help admins recognize which users are which.

An alternate, and cleaner approach would be the face-only user skin method implemented by Dynmap.

That is a very valid idea, But unfortunately since this plugin does not use a Jar file it uses mySQL and MySQL only. This feature may be a little difficult to add. As can be seen in this picture it is much easier to reporuduce these images due to the fact that Logblock has a Jar file as well as the PHP files (If that makes any sense). It should be possible though
