MIME type warning in chrome for png images

Question

Just ran my site in chrome and suprisingly it comes up with this warning for each of my .png images:

Resource interpreted as image but transferred with MIME          


        

Answer 1

Ofcourse above solutions are perfect. Just to avoid warnings and for a clean console I done following change in my code. (that too only for ASP.NET Development Server) I written a extra handler for this:

PNGHandler.cs

class PNGHandler : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    { 
       if(context.Request.HttpMethod == "GET") 
       {
             string requestedFile = context.Server.MapPath(context.Request.FilePath);
             FileInfo fileinfo = new FileInfo(requestedFile);
             string contentType = "";
             if (fileinfo.Exists && fileinfo.Extension.Remove(0, 1).ToUpper() == "PNG")
             {
                   contentType = "image/png";
                   context.Response.ContentType = contentType;
                   context.Response.TransmitFile(requestedFile);
                   context.Response.End();
              }
         }
    }
}

And added Http Handler in web.config under system.web
