CSS

#chartPreview
        {
            position:fixed;
        }.imgPreview
        {
            display:none;   
        }

and here is my jquery

JavaScript

$j(document).ready(function ($) {
                $j('#delete').hide();
                $j('#upload').click(function ($) {
                    $j('#<%= fuFiles.ClientID%>').click();
                });
                $j('#delete').click(function ($) {
                    $j('#imgPreview').hide();
                    $j('#upload').show();
                    $j('#<%= fuFiles.ClientID%>').attr('value', '');
                    $j('#delete').hide();
                    $j('#<%= btnImageSend.ClientID %>').hide();                    
                    $j('#btnSave').show();
                    $j('#<%= txtShout.ClientID %>').css('height','30');

                });
            });

            function readURL(input) {
                if (input.files && input.files[0]) {
                    var reader = new FileReader();
                    reader.onload = function (e) {
                        $j('#imgPreview').show();
                        $j('#upload').hide();
                        $j('#chartPreview').attr('src', e.target.result);
                        $j('#delete').show();
                        $j('#<%= txtShout.ClientID %>').css('height', '90');
                        $j('#<%= btnImageSend.ClientID %>').show();
                        $j('#btnSave').hide();
                    }
                    reader.readAsDataURL(input.files[0]);
                }
            }

            $j(document).ready(function ($) {
                $j("#<%= fuFiles.ClientID %>").change(function ($) {
                    readURL(this);
                    document.getElementById("<%= hdnFile.ClientID %>").value = "N";
                    $j('#<%= txtShout.ClientID %>').css('height', '90');
                });
            });
