Image Not Shown In IIS7

I faced some problems after hosting my web project in IIS 7 / Windows 2008. Images are not shown when I run the project on my browser.

I copied my project folder (webtest) to c:\inetpub\wwwroot\. To be sure, I chose image from webtest\image\sample.jpg again. It works properly when I run it. However, after putting up for hosting and I cal开发者_Go百科l it from browser it doesn't show the image.

What are the possible causes of the problem?

Possible solution is to add .jpg/.jpeg mime type in IIS Manager if it doesn't exists.
