Generally speaking, when running an ASP.NET site locally, if the URL host name is simply localhost on the default port, the site is hosted in IIS. If the URL host name includes a random high-order port, then the site probably runs on the Visual Studio development server.

You can configure how the development site is hosted on the Web tab of your project settings, if using a Web Application Project. If using a Web Site, hosting the site in IIS requires that you configure the site’s virtual folder in IIS manually, and re-add the web site to your solution from IIS, instead of from the file system.

To resolve issues with your image references breaking, there are a few things you can check:

• When using server controls for images, favor prefixing your ImageUrl attributes with a tilde-slash (~/), which the server will resolve relative to the web application folder.
• When referencing images outside of your web application (e.g. some other parent, such as a sibling or a parent, ensure you have configured your site on IIS and that the dependencies are also installed on IIS in the correct location relative to your development site.
• Finally, if these actions do not resolve the issue, consider monitoring your network traffic with Fiddler. This tool will enable you to see what images the browser actually requests, and diagnose where the assumptions went wrong. (Note that Fiddler won’t listen on localhost. I have to use my machine’s DNS name or IP address to capture requests from Fiddler on my local machine.)
