c# - convert from physical path to virtual path

I have this function that gets the fileData as a byte array and a file path. The error I am getting is when it tries to set the fileInfo in the code bewlo. It says 'Physical Path given, Virtual Path expected'

 public override void WriteBinaryStorage(byte[] fileData, string filePath)
    {
        try
        {
            // Create directory if not exists.
            System.IO.FileInfo fileInfo = new System.IO.FileInfo(System.Web.HttpContext.Current.Server.MapPath(filePath)); //when it gets to this line the error is caught
            if (!fileInfo.Directory.Exists)
            {
                fileInfo.Directory.Create();
            }

            // Write the binary content.
            System.IO.File.WriteAllBytes(System.Web.HttpContext.Current.Server.MapPath(filePath), fileData);
        }
        catch (Exception)
        {
            throw;
        }
    }

When debugging it, is providing the filePath as "E:\WEBS\webapp\default\images\mains\myimage.jpg" . And the error message is

'E:/WEBS/webapp/default/images/mains/myimage.jpg' is a physical path, but a virtual path was expected.

Also, what it is triggering this to happen is the following call

properties.ResizeImage(imageName, Configurations.ConfigSettings.MaxImageSize, Server.MapPath(Configurations.EnvironmentConfig.LargeImagePath));

If you already have a physical path, it doesn't make sense to call Server.MapPath.

You're calling MapPath twice.
