hi i used to use this image and the link was

<img id="reminder_{vb:raw favid}_toggler" src="clear.gif" class="reminder_toggler<vb:if condition="$show['fav']">_active</vb:if>" onclick="FAVReminder.Toggle({vb:raw favid});" title="<vb:if condition="$show['fav']">Remove Favorite<vb:else />Add Favorite</vb:if>" />

and the code in .js file code is:

PHP Code:

FAVReminder = new reminder();

function reminder()
{
    this.Toggle = function(favid)
    {
        SitePopup.Show('FAV Reminder',PHRASE_AJAX_RUNNING);
        
        YAHOO.util.Connect.asyncRequest("POST", "ajax.php", {
                success: this.ProcessReminder,
                failure: this.handle_ajax_error,
                timeout: vB_Default_Timeout,
                scope: this
            }, SESSIONURL + 'securitytoken=' + SECURITYTOKEN + '&do=togglereminder&favid=' + favid);
            
    }
    
    this.handle_ajax_error = function(ajax)
    {
        //TODO: Something bad happened, try again
        vBulletin_AJAX_Error_Handler(ajax);
    }
    
    this.ProcessReminder = function(ajax)
    {
        if (ajax.responseXML)
        {
            var error = ajax_fetch_tag('error', ajax);
            var reminder = ajax_fetch_tag('reminder', ajax);
            var nzbfavcache = ajax_fetch_tag('favcache', ajax);
            var nzbid = ajax_fetch_tag('favid', ajax);

            if (error)
            {
                SitePopup.Show('FAV Reminder...', error);
            }
            else
            {
                SitePopup.Show('FAV Reminder', PHRASE_AJAX_COMPLETE);
                SitePopup.TimerClose(1000);        
                

                if (toggler = fetch_object('reminder_' + favid+ '_toggler'))
                {
                    toggler.className = 'reminder_toggler' + ( reminder == 0 ? '' : '_active' );
                    toggler.title = ( reminder == 1 ? 'Remove Favorite' : 'Add Favorite' );

                }
                if (togglertitle = fetch_object('add_' + favid + '_remove'))
                {
                    togglertitle.innerHTML = ( reminder == 1 ? 'Remove Favorite' : 'Add Favorite' );

                }
                if (titlecell = fetch_object('td_threadtitle_' + favid), true)
                {
                    reminderthreadhighlight(titlecell, ( reminder == 0 ? 'remove' : 'add' ),1);
                }
                if (img = fetch_object('reminder_' + favid + '_img'))
                {
                    img.style.display = ( reminder == 0 ? 'none' : '' );
                }
            }
        }
    }
}
