盗链163、百度、QQ空间图片 不指定

收藏到网摘：

有时在BBS上面发帖子时要引用一些来自163、百度、QQ空间等的图片，像这些比较大一点的相册站，一般都会加上防盗链，他会检测图片请求的来源。如果来源不是本站，就会显视成特定的图片如：
百度相册 右边这个图就是使用的这个功能所显视出来的原图
163相册或博客
它就不会显视原来的图片。好了破解方法如下：（来源网络）

使用 http://www.iqshw.com/tu.asp?url=
再加图片地址 就可以正常使用，而没有盗链提示了

另外附上一个ASp程序。就是上面这个连接中tu.asp中的源码把它保存为PIC.asp传到你的空间就可以用了。 方法http://你的域名/pic.asp?url=这里改成图片地址就可以了 他还可以用在别的网站有防盗链图片中
