Tip If you want to add a picture and a caption to a command button, you can create the picture and caption in Microsoft Windows Paint. To create a picture the size of your button using Paint, draw the picture on a background of any size, and then select only the portion that will fit on your button. On the Edit menu, click Copy To and specify a file name in the Save As dialog box. This creates a file with a picture of the exact size that you selected.
