Asp.net MVC page is giving Mime type warnings for image files

While I do not see any functionally or jquery UI elements affected by this, but when I access my asp.net mvc web page the chrome developer console is logged with a bunch of error messages like so:

Resource interpreted as image but transferred with MIME type application/octet-stream.

All of the warnings are for jquery UI images (though I don't have any custom images on there so I don't know if it's jquery UI only). All the jquery images still load correctly.

Does anyone have 开发者_StackOverflow中文版any insight on why this is happening?

Are you running your site from Visual Studio's built-in web server? Apparently, you don't have much control over the MIME types in that environment (see this). I was seeing the same behavior and was starting to stress about it before finally realizing that I wasn't even looking at the IIS-hosted application.
