Make Application_BeginRequest process the entire request, including static files

How can I get Application_BeginRequest to process every single request, including static files?

Global.ascx.cs

protected void Application_BeginRequest()
{

}

I currently have this on my web.config

<system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
    </modules>
</system.webServer>

I am using II7 and my application pool is integrated as a managed pipeline mode.

In this current state, it fires an event for .aspx pages, but not for files such as images.
