Как разместить изображение из нашего приложения в linkedin post ?

I have to post image to the linkedin from my asp.net mvc applicaiton.

<blockquote class="quote"><div class="op">Quote:</div> function ShareLinkedIn() {
            var Array = $('#VacancyGrid [name=id]:checked').map(function() {
                return $(this).val();
            }).get();

            if (Array == "") {
                showAlertMessage("Alert", "Please select vacancy."); // alert();
            } else {

                $.ajax({
                    url: '@Url.Action("LinkedINAuth", "Vacancy")',
                    data: { vacancyIds: Array.toString() },
                    async: true,
                    type: 'POST',
                    cache: false,
                    success: function(datas) {
                        debugger;
                        var html = datas.split(',')[0].toString();
                        var image = datas.split(',')[1].toString();
                        //txp2rKYpuKZXaaYC5kB-m13KnVE Initialize with your OAuth.io app public key  QdDTUvqmt2uX6kg4M5Fonvyn7c4
                        OAuth.initialize('txp2rKYpuKZXaaYC5kB-m13KnVE');
                        // $('#auth').show();
                        OAuth.popup('linkedin2').then(linkedin => {
                            console.log('linkedin:', linkedin);
                        // Get your linkedin profile id:
                        linkedin.me().then(data => {
