  Hello,
  
  If you don't need full-size images, you may use thumbnails. To do this, clear the ImageLocation property of the Picture object and create the BeforePrint event handler:
  

  private void Picture1_BeforePrint(object sender, EventArgs e)
  {
    string fileName = ((String)Report.GetColumnValue("db_hamapict.fld_bilddatei"));
    using (Bitmap bmp = new Bitmap(fileName))
    {
      // create 400x300 pixels thumbnail 
      Picture1.Image = bmp.GetThumbnailImage(400, 300, null, IntPtr.Zero);
    }
  }

  Hi
  
  Sounds very good. Thank you.
  
  I have copy the code an editet to my environment. But unfortunately I get an other Error.
  
  
  MyCode now:
  private void Image_BeforePrint(object sender, EventArgs e)
  {
  string fileName = ((String)Report.GetColumnValue("db_hamapict.fld_bilddatei"));
  using (Bitmap bmp = new Bitmap(fileName))
  {
  // create 400x300 pixels thumbnail
  Image.Image = bmp.GetThumbnailImage(400, 300, null, IntPtr.Zero);
  }
  }

  ************** JIT-Debuggen **************
  Um das JIT-Debuggen (Just-In-Time) zu aktivieren, muss in der
  Konfigurationsdatei der Anwendung oder des Computers
  (machine.config) der jitDebugging-Wert im Abschnitt system.windows.forms festgelegt werden.
  Die Anwendung muss mit aktiviertem Debuggen kompiliert werden.
  
  Zum Beispiel:
  
  <configuration>
  <system.windows.forms jitDebugging="true" />
  </configuration>
  
  Wenn das JIT-Debuggen aktiviert ist, werden alle nicht behandelten
  Ausnahmen an den JIT-Debugger gesendet, der auf dem
  Computer registriert ist, und nicht in diesem Dialogfeld behandelt.
  
  
  Any Ideas ? The Idea with the Thumbnail sounds very nice, i think with this Idea we are on the right course.
  
  Greetings.

  Hello,
  
  Most probably, you pass wrong fileName (file not exist, or bad-formed path) to the Bitmap constructor.
  The correct code that checks for file existence:
  

  private void Picture1_BeforePrint(object sender, EventArgs e)
  {
    string fileName = ((String)Report.GetColumnValue("db_hamapict.fld_bilddatei"));
    if (!System.IO.File.Exists(fileName))
    {
      Picture1.Image = null;
      return;
    }
  
    using (Bitmap bmp = new Bitmap(fileName))
    {
      // create 400x300 pixels thumbnail
      Picture1.Image = bmp.GetThumbnailImage(400, 300, null, IntPtr.Zero);
    }
  }

  Hmmm, one new Problem [img]style_emoticons/<#EMO_DIR#>/dry.gif" style="vertical-align:middle" emoid="<_<" border="0" alt="dry.gif" /> If the Format of the Picture is Portrait the Image was not correct displayed because the Definition of: // create 400x300 pixels thumbnail Picture1.Image = bmp.GetThumbnailImage(400, 300, null, IntPtr.Zero); Is there a possibility to create the Thumbnails dynamic ? Thank's for any Answer.[/img]

  Use ratio instead of hardcoded sizes:
  

  float ratio = 0.3f;
  // you can even make ratio dynamic, depending on original image size
  if (bmp.Width < 1000)
    ratio = 0.5f;
  if (bmp.Width < 500)
    ratio = 0.7f;
  Picture1.Image = bmp.GetThumbnailImage((int)Math.Round(bmp.Width * ratio), (int)Math.Round(bmp.Height * ratio), null, IntPtr.Zero);
