C# - Controller Path Not Found For Static Images?

I have an image folder stored at ~/Content/Images/

I am loading these images via

<img src="/Content/Images/Image.png" />

Recently, the images aren't loading and I am getting the following errors in my error log. What's weird is that some images load fine, while others do not load.

what is wrong with my routes? Am I missing an ignore route for the /Content/ folder?

I am also getting the same error for favicon.ico and a bunch of other image files...

My current routes look like this:

routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
routes.MapRoute(
"Default", // Route name
"{controller}/{action}/{id}", // URL with parameters
new { controller = "Home", action = "Index", id = "" } // Parameter defaults
);
routes.MapRoute(
"ControllerDefault", // Route name
"{controller}/project/{projectid}/{action}/{searchid}", // URL with parameters
new { controller = "Listen", action = "Index", searchid = "" } // Parameter defaults
);
