Answer 1

If this key is in your web.config file

<appSettings>
  <add key="ImagePath" value="\Images\"/>
</appSettings>

Then in your server-side code, you can get the image path from configuration to get the Physical Path for storage like so:

var imagePath = ConfigurationManager.AppSettings["ImagePath"];
var physicalPath = Server.MapPath(imagePath);

if (File.Exists(physicalPath))
{
    //... store your images ...
}

This sounds like a permissions issue.

When the IIS worker process tries to write to the /Images/ folder, it is unable as it does not have write permissions. When you run your website locally via Visual Studio it gives the worker process full rights to any folder in your solution - this may be why you can run it locally but not on the server.

You would need to give the IIS worker process user both Read and Write access to the /Images/ folder.

However you must ensure you do not give your IIS Worker process user the Read & Execute permission.
