"I'd suggest you start only one background worker which produces the thumbnails in a loop and after each one you use its method ReportProgress"

Like this?
void BackgroundWorker1DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
    for (var i = 0; i < fileList.Count; i++)
    {
        Bitmap thumbnail = MakeThumbnail(fileList[i], 200, 200);
        backgroundWorker1.ReportProgress(i);
    }
}


"but not for reporting the progress-percentage like in the sample but using the other member of ProgressChangedEventArgs[^] (UserState) to deliver the thumbnail bitmap to your UI thread."

This is unclear to me. How do I actually use UserState to deliver the thumbnail? That MSDN example is very simplistic (it just shows UserState). This is advanced stuff for me.
