文本内容中发现无效字符。处理资源 'http://localhost:7151/WebOne/MakeImage.ashx' 时出错。@H_403_2@
而用firefox和chrome测试却并未报错，纠结了老半天才发现原来是设置了context.Response.ContentType = "image/jpg"的原因,遂将context.Response.ContentType = "image/jpg"语句删除，IE8打开页面显示成功!但是在firefox、chrome里打开却出现了乱码。@H_403_2@
随后在网上找原因，原来是”image/jpep“而不是“image/jpg"，改动后各浏览器测试良好@H_403_2@
