                     if(typeof(data.error) != 'undefined')
                    {
                        if(data.error != '')
                        {
                            alert(data.error);
                        }else
                        {
                            alert(data.msg);
                            showprofilepicture();
                        }
                    }
                }

            }
        ) 

the function showprofilepicture() also not excuted.

The jQuery.handleError was removed after the jQuery version in 1.5 you need to write a custom error handler function to solve this like

jQuery.extend({
    handleError: function( s, xhr, status, e ) {
        // If a local callback was specified, fire it
        if ( s.error )
            s.error( xhr, status, e );
        // If we have some XML response text (e.g. from an AJAX call) then log it in the console
        else if(xhr.responseText)
            console.log(xhr.responseText);
    }
});

             if(typeof(data.error) != 'undefined')
            {
                if(data.error != '')
                {
                    alert(data.error);
                }else
                {
                    alert(data.msg);
                    showprofilepicture();
                }
            }

should be

jQuery.ajaxFileUpload({
            url:'<?php echo $currenturl."&fileupload=enable";?>',
            secureuri:false,
            fileElementId:'fileToUpload',
            dataType: 'json',
            data:{'image_desc':image_desc,'gallery_id':curr_time_stamp},
            success: function (data, status)
            {   

                 if(typeof(data.error) != 'undefined')
                {
                    if(data.error != '')
                    {
                        alert(data.error);
                    }
                }else
                    {
                        alert(data.msg);
                        showprofilepicture();
                    }
            }

        }
    )
