I've noticed an issue with just added docker badges: while repo name on github can use upper case letters (like yours, mine, and I suppose it's usual case for Perl modules on github) related repo on hub.docker.com will be always lower case. Even if I try to create docker repo using upper case it converts it to lower case and url with original upper case name returns 404. Same happens for user name - I've just tried to create account with upper case on docker hub to test this.
Not sure is this issue also affect other badges, so I've fixed only docker's.
