     '                           cell in the range will be used.
     '             imagePath   - The path to the image you want to use.
     '             imageHeight - Optional. Sets the height of the image.
     '             imageWidth  - Optional. Sets the width of the image.
     '             overWrite   - Optional. If a comment already exists in cell

     '                           then the comment will be overwritten. Otherwise
