In the click live handlers, you're only setting the value of the value parameter. You're not executing the rest of the code after that. Try something like this (untested):

function manageVoting() {
    var parameter;
    var myVoting;
    var divVoting;
    var divVotes;
    var value = -1;
    var parameterData;
    $('div.votemaincontainer').each(function() {
        parameter = $(this).find('#[id$= hfUrl]').val();
        myVoting = parseInt($(this).find('#[id$=hfMyVote]').val());
        divVoting = $(this).find('[id$=divVoting]');
        divVotes = $(this).find('[id$=divVotes]');

        function processVote(value) {
            if (value == 0 || value == 1) {
                parameterData = parameter + value + "'}";

                $.ajax({
                    type: 'POST',
                    url: 'UserControls/Vote/VoteAction.aspx/Voting',
                    data: parameterData,
                    contentType: "application/json; charset=utf-8",
                    dataType: "json",
                    success: function(data) {
                        var result = eval(data.d);

                        if (result) {
                            if (result.length > 1) {
                                alert("i am inside result here result length >1");
                                if (result[1] == 1 && result[2] == 1) 
                                {
                                    $('img.voteupImage').attr('src', 'UserControls/Vote/Images/aftervote_arrow_up.png');
                                    $('img.votedownImage').attr('src', 'UserControls/Vote/Images/arrow_down.png');
                                    $('div.divVotes').html(result[0]);
                                }
                                else 
                                {
                                    alert('U can not vote more than 1');
                                }
                                $('#[id$=hfMyVote]').html(result[1]);
                                if (result[1] == 0 && result[2] == 1)

                                }
                                else 
                                {
                                    alert('U can not vote down more than 1');

                            }

                        }
                    },
                    error: function() {
                        alert("i am inside error");

                    }
                });
            }
        }

        $('img.voteupImage').live('click', function() {
            if (myVoting == 1) {
                alert(" you have already voted");
            }
            else {
                value = 1;
                processVote(value);
            }
        });
        $('img.votedownImage').live('click', function() {
            if (myVoting == 0) {

            else {
                value = 0;

        });
    });

Also, when you're using the JSON data type with $.ajax, you shouldn't need to eval the data that comes back. jQuery already evaluates the JSON for you, and returns a native JavaScript object.
