How to Reduce a Picture to a Thumbnail in VB6
Visual Basic 6, or VB6, allows a wide array of computer functions, controlled via command-line interface. One of these will reduce a picture to a thumbnail. This is useful if you want to put a photo online or send a smaller version to a friend. You can customize the size of the thumbnail in VB6 to any dimensions you choose. It will save the thumbnail in the same folder as the original.
