freetextbox 只能显示两张图片 user defined custom images (here, we're just allowing the first two)

// modify the images allowed
	if (currentFolder == "~/images") {

		System.IO.DirectoryInfo directoryInfo = new System.IO.DirectoryInfo(Server.MapPath(currentFolder));

		// these are the default images FTB:ImageGallery will find
		System.IO.FileInfo[] defaultImages = directoryInfo.GetFiles("*");

        System.Collections.Generic.List<System.IO.FileInfo> imgs = new System.Collections.Generic.List<System.IO.FileInfo>();
        foreach (System.IO.FileInfo img in defaultImages)
        {
            imgs.Add(img);
        }
        
		// user defined custom images (here, we're just allowing the first two)
        System.IO.FileInfo[] customImages = imgs.ToArray(); //new System.IO.FileInfo[2] {defaultImages[0], defaultImages[1]};
		
		// the gallery will use these images in this instance
		ImageGallery1.CurrentImages = customImages;
	}	

使用泛型即可解决问题，修改ftb.imagegallery.aspx事件中相应的代码 protected void Page_Load(Object Src, EventArgs E) 如上！
