You can use Task Parallel Library to achieve that. Something like:

I would use the BackgroundWorker class (also see this tutorial) to generate the thumbnails in the background. Something like:

BackgroundWorker imageGenerator = new BackgroundWorker()

foreach(var filename in imageFileNames)
{
    imageGenerator.DoWork += (s, a) => GenerateThumbnailMethod(filename);
}

imageGenerator.RunWorkerAsync();

This will generate the thumbnails on a separate thread. You can also get the BackgroundWorker to let you know when it's done by assigning an event handler to its RunWorkerCompleted event. You should do this, because this allows for error checking, as the RunWorkerCompletedEventArgs object has an Error property.
