Hi Byron,
I do understand how the plug-in works with regard to voting and collecting results for anonymous users. The reason I want to allow an anonymous person from the same IP to vote over and over again is because a large number of the people voting on images all share the same external IP address. (They are all in the same office.)
I do realize that this will allow an individual to vote for the same image over and over again but I would rather allow for that risk than limit the vote to one per all users on the same IP. So that is why I'm asking if there is any small modification I could make (and where?) to remove the 'one vote per picture per IP address' rule.
A possible future enhancement could be limiting voting by setting a cookie. Obviously this could be fooled by someone clearing cookies... but is there any perfect way to allow multiple people from shared IPs to vote without the possibility of someone gaming the system?
