IE空圖像=紅色十字： -/

當我的圖像是空的時，IE將它繪製爲紅色十字。有什麼辦法可以避免畫紅十字？IE空圖像=紅色十字： -/

或因爲我有asp圖片我可以使它不可見，但是然後我需要檢查這個圖像是否包含一些東西。

<asp:Image ID="Image1" runat="server" ImageUrl="Handler.ashx"/>

我需要加載到byte [] x = {??? };一個白色像素在圖像/ jpeg格式

我的解決方案讓我瘋狂！這裏是：

<%@ WebHandler Language="C#" Class="Handler" %> 

using System; 
using System.IO; 
using System.Web; 
using Auth; 

using System.Configuration; 

public class Handler : IHttpHandler

    public bool IsReusable 
    { get{ return false; } } 

    public void ProcessRequest(HttpContext context) 
    { 
     context.Response.Clear(); 
     context.Response.ContentType = "image/jpeg"; 
      byte[] imageContent = Auth.User.GetImageFromDataBase(); 
      if (imageContent != null) 
       context.Response.OutputStream.Write(imageContent, 0, imageContent.Length); 
      else 
      { 
       byte[] x = {0xff, 0xd8, 0xff, 0xe0, 0x0, 0x10, 0x4a, 0x46, 0x49, 0x46, 0x0, 0x1, 0x2, 0x0, 0x0, 0x64,

在這裏也搜索「破碎的圖像」，這會給你一些替代選項。 – Lazarus 2010-02-03 11:13:47

@Lazarus你是什麼意思？。。。 – Cynede 2010-02-03 11:39:58

使用本頁頂部的搜索字段來搜索「破碎的圖像」，您將看到與您遇到的相同問題相關的所有問題和答案，例如，指向不再存在或已存在圖像的img標籤已被移動。 – Lazarus 2010-02-03 12:06:32

這是更好地展示一個默認的圖像，如果圖像是在handler.ashx文件是空的。我們在內部網上爲電話簿做同樣的事情。

...這是可能的，但我不需要默認圖像。我想我會使用它，如果我找不到解決方案如何隱藏十字架:)謝謝。 – Cynede 2010-02-03 11:06:41

@nCdy，爲了增加Shoban的回覆，你可以將默認圖片設置爲1px×1px透明gif，這樣最終用戶不會感覺到它。 – 2010-02-03 11:07:46
