在IIS7中无法显示axd中的图片的解决方法

原因：IIS7服务器默认没有支持axd格式的MIME。

解决方法：通过修改Web.config来解决。

	<system.webServer>
		<validation validateIntegratedModeConfiguration="false"/>
		<modules>
			<remove name="ScriptModule"/>
			<add name="ScriptModule" preCondition="managedHandler" type="System.Web.Handlers.ScriptModule, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
		</modules>
		<handlers>
			<remove name="WebServiceHandlerFactory-Integrated"/>
			<remove name="ScriptHandlerFactory"/>
			<remove name="ScriptHandlerFactoryAppServices"/>
			<remove name="ScriptResource"/>
			<add name="ScriptHandlerFactory" verb="*" path="*.asmx" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
			<add name="ScriptHandlerFactoryAppServices" verb="*" path="*_AppService.axd" preCondition="integratedMode" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
			<add name="ScriptResource" preCondition="integratedMode" verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35"/>
            <add name="WebResource" verb="GET" path="WebResource.axd"  preCondition="integratedMode" type="System.Web.Handlers.AssemblyResourceLoader"/>
			<add name="cachedimageservice" verb="GET" path="cachedimageservice.axd"  preCondition="integratedMode" type="MsdnMag.CachedImageService,DynamicImage"/>
			<add name="Reserved.ReportViewerWebControl" verb="*" path="Reserved.ReportViewerWebControl.axd" preCondition="integratedMode" type="Microsoft.Reporting.WebForms.HttpHandler, Microsoft.ReportViewer.WebForms, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
		</handlers>
        <staticContent>
            <remove fileExtension=".axd" />
            <mimeMap fileExtension=".axd" mimeType="image/bmp" />
        </staticContent>
	</system.webServer>

关键是其中跟axd相关的配置。
