Uploading images

I am a beginner and this is my very first website project.

I am populating an array using Server.MapPath. On my local machine it is trying to read from
C:\Documents and Settings\\My Documents\Visual Studio 2008\Projects folder. I thought the Server.MapPath would read from C:\inetpub\wwwroot.
The array I am creating is getting all images from a folder. I want to allow the user to upload images to this folder. When I save the images from the user the images are being stored in C:\inetpub\wwwroot on my local machine.

here is my save path
        string savePath = @"c:\inetpub\wwwroot\SlideShow\Files\" + folderName;

this is how I retrieve the images
    protected void Page_Load(object sender, EventArgs e)
    {
        //create a string to hold the images for the banner
        StringBuilder imageArray = new StringBuilder();
        imageArray = GetImageArray(ResolveClientUrl(folderName));
        //register array so it can be referenced in javascript
        ClientScriptManager csm = Page.ClientScript;
        csm.RegisterArrayDeclaration("Pictures", imageArray.ToString());

    protected StringBuilder GetImageArray(string folderName)
    {
        string Path;
        DirectoryInfo Folder;

        FileInfo[] Images;
        StringBuilder ImageArray = new StringBuilder();

        Path = Server.MapPath(folderName);
        Folder = new DirectoryInfo(Path);
        Images = Folder.GetFiles();
               
        // Looping through all files in the folder and generating
        // a JavaScript array declaration.
        foreach (FileInfo Image in Images)
        {
            if (Image.Extension.StartsWith(".jpg") || Image.Extension.StartsWith(".JPG"))
                ImageArray.AppendFormat("'{0}/{1}',", folderName, Image.Name);
            else
                continue;
        }

        if (ImageArray.Length > 0)
        {
            // Removing the unwanted last comma.
            ImageArray.Remove(ImageArray.Length - 1, 1);
        }

        return ImageArray;
    }

Would I be better off saving the images with something similar to server.mappath rather than writing out  @"c:\inetpub\wwwroot\SlideShow\Files\"?

Yes, you should never hard code paths, if you need to use the full path like that you can use the web.config file to store configuration...

use
Path = Server.MapPath(folderName);

the best way to code is using \ and ..\ instead of hardcoding the C:\......

>>>On my local machine it is trying to read from
C:\Documents and Settings\\My Documents\Visual Studio 2008\Projects folder
Is this the folder that you have all your ASPX files in?
>>>string savePath = @"c:\inetpub\wwwroot\SlideShow\Files\" + folderName;
Is "SlideShow" the virtual directory of your application?

I did deploy it and checked it and it worked. I was just kinda fuzzy on why Server.MapPath was reading files from the visualstudio/projects folder on my local machine when Server.MapPath was storing images in c:\inetpub\wwwroot\SlideShow\.............  on my local machine. But it is working on the server. I am learning new things and discovering new things each day I work on this. Thanks guys..gals?.....
