Hi,

You can use the following,

XML

<script type="text/javascript">
    function fileCheck(obj) {
            var fileExtension = ['jpeg', 'jpg', 'png', 'gif', 'bmp'];
            if ($.inArray($(obj).val().split('.').pop().toLowerCase(), fileExtension) == -1)
                alert("Only '.jpeg','.jpg', '.png', '.gif', '.bmp' formats are allowed.");
    }
</script>

<asp:FileUpload ID="FileUpload1" runat="server"  onchange="fileCheck(this);"/>
