+# How to: Create Thumbnail Images
+A thumbnail image is a small version of an image. You can create a thumbnail image by calling the <xref:System.Drawing.Image.GetThumbnailImage%2A> method of an <xref:System.Drawing.Image> object.  
+  
+## Example  
+ The following example constructs an <xref:System.Drawing.Image> object from a JPG file. The original image has a width of 640 pixels and a height of 479 pixels. The code creates a thumbnail image that has a width of 100 pixels and a height of 100 pixels.  
+  
+ The following illustration shows the thumbnail image:  
+  
+ ![Screenshot that shows the output thumbnail.](./media/how-to-create-thumbnail-images/construct-thumbnail-image.png)  
+  
+> [!NOTE]
+> In this example, a callback method is declared, but never used. This supports all versions of GDI+.

+ [!code-vb[System.Drawing.WorkingWithImages#71](~/samples/snippets/visualbasic/VS_Snippets_Winforms/System.Drawing.WorkingWithImages/VB/Class1.vb#71)]  
+  
+## Compiling the Code  
+ The preceding example is designed for use with Windows Forms, and it requires <xref:System.Windows.Forms.PaintEventArgs> `e`, which is a parameter of the <xref:System.Windows.Forms.Control.Paint> event handler. To run the example, follow these steps:  
+  
+1. Create a new Windows Forms application.  
+  
+2. Add the example code to the form.  
+  
+3. Create a handler for the form's <xref:System.Windows.Forms.Control.Paint> event  
+  
+4. In the <xref:System.Windows.Forms.Control.Paint> handler, call the `GetThumbnail` method and pass `e` for <xref:System.Windows.Forms.PaintEventArgs>.  
+  
+5. Find an image file that you want to make a thumbnail of.  
+  
+6. In the `GetThumbnail` method, specify the path and file name to your image.  
+  
+7. Press F5 to run the example.  
+  
+     A 100 by 100 thumbnail image appears on the form.
