My asp.net application saving a long list of image files and then have to view one of them. The client can browse the images, But its take a long time. I have a dictionary with key - file path and value -Image: 

Dictionary<string, System.Drawing.Image> imageList = new Dictionary<string,System.Drawing.Image>(); 
//filling imageList
foreach (KeyValuePair<imagePath, System.Drawing.Image> item in imageList)
{
    item.Value.Save(item.Key, System.Drawing.Imaging.ImageFormat.Jpeg);
}

I am looking for some way to save just one image file, make response, and continue saving the other image files, there is any way to do it? maybe with Thread? Thanks!

    Disk IO may be very slow, nevertheless you can try this 

    foreach (KeyValuePair<string, System.Drawing.Image> item in imageList)
        Task.Factory.StartNew(() =>
        {
            lock (item.Value)
                item.Value.Save(item.Key, System.Drawing.Imaging.ImageFormat.Jpeg);
        });

    I put the images saving in thread block and it works perfectly and fast: 

    Dictionary<string, System.Drawing.Image> imageList =new Dictionary<string,System.Drawing.Image>(); 
    //filling imageList 
    Thread thread = new Thread(() =>{
       foreach(KeyValuePair<string, System.Drawing.Image> image in imageList)    {
           image.Value.Save(item.Key,System.Drawing.Imaging.ImageFormat.Jpeg);
        }
    });
    thread.Start();
