ผมลองเขียน jQuery Plugin มีท่านช่วยว่าต้องแก้ไขตรงได้ไหมครับ

(function($) {
	    $.fn.ExpandableAdsHeader = function(options)
	{
				
		ObjAds = $(this);
		ObjImgNormal = $(this).find("img")[0];
		ObjImgActive = $(this).find("img")[1];
		ObjImgClose  = $(this).find("img")[2];
		
		$(ObjAds).css("width",options.ads_width);
		$(ObjAds).css("height",options.ads_height);
		
		if(options.show_border)
		{
			$(ObjAds).css("border","#666 solid 1px");
		}
		
		$(ObjImgNormal).css("position","absolute");
		
		$(ObjImgActive).css("display","none");
		$(ObjImgActive).css("position","absolute");
		
		$(ObjImgClose).css("width",options.bt_close_width);
		$(ObjImgClose).css("height", options.bt_close_height);
		$(ObjImgClose).css("display","none");
		$(ObjImgClose).css("cursor","pointer");
		$(ObjImgClose).css("position","relative");
		$(ObjImgClose).css("left",options.bt_close_x);
		$(ObjImgClose).css("top",options.bt_close_y);
		
		$(this).hover(function()
		{
			$(ObjImgNormal).fadeOut(options.time_fadeout);
			$(this).animate({paddingBottom:options.active_height}, options.time_animation, function()
			{
				$(ObjImgActive).fadeIn(options.time_fadein);
				$(ObjImgClose).fadeIn(options.time_fadein);
				$(ObjImgActive).css("display","block");
				$(ObjImgClose).css("display","block");
			}).off('hover');
		});

		$(ObjImgClose).click(function()
		{
			$(ObjImgActive).fadeOut(options.time_fadeout);
			$(ObjImgActive).css("display","none");
			$(ObjImgClose).fadeOut(options.time_fadeout);
			$(ObjImgClose).css("display","none");
			$(ObjImgNormal).fadeIn(options.time_fadein);
			
			
			$(ObjAds).animate({paddingBottom:'0px'}, options.time_animation, function()
			{
				$(this).on('hover', function()
				{
					$(ObjImgNormal).fadeOut(options.time_fadeout);
					$(this).animate({paddingBottom:options.active_height}, options.time_animation, function()
					{ 
						$(ObjImgActive).fadeIn(options.time_fadein);
						$(ObjImgClose).fadeIn(options.time_fadein);
						$(ObjImgActive).css("display","block");
						$(ObjImgClose).css("display","block");
					}).off('hover');
