Check this
private byte[] ReadImage(string filename)
    {
        
        try
        {
                FileStream fs = new FileStream(filename, FileMode.Open, FileAccess.Read);
 
                BinaryReader br = new BinaryReader(fs);
 
                byte[] image = br.ReadBytes((int)fs.Length);
 
                br.Close();
 
                fs.Close();
 
                return image;
            
        }
        catch (Exception ex)
        {
            throw ex;
        }
    }

Also you can use:
byte[] myImageBytes = System.IO.File.ReadAllBytes("MyImageFilePath");

Where image (trying to convert to byte array) is located?
OR  You are using file upload control and convert it into byte array and saving it into database?

If the image is in folder then you can get the correct path like

Server.MapPath("~/images/your_image_name");

Check that your file exists in "C:\Documents and Settings\Administrator\Desktop\paintec.co.za\images\", have you mistype "no image.jp"? try "no image.jpg"

If you are giving hardcode path
then path could be

 string filename=@"C:\Documents and Settings\Administrator\Desktop\paintec.co.za\images\your_image_name.jpg";

OR

 string filename="C:\\Documents and Settings\\Administrator\\Desktop\\paintec.co.za\\images\\your_image_name.jpg";
