Hi Phil,

You can capture the Spectrogram images by pressing "Alt- Print Screen" while the image is displayed.
Then you can use "Control-V" to paste the image into a paint program such as Paint Shop Pro, Paint Shop, or even the Microsoft Paint
program that comes with Windows.

Then you can add annotation to the image with the text and line drawing tools.

Save the image as a gif (prefered) or a bmp.  These result in larger files than jpg, but jpg causes line drawings
to become fuzzy.

Here's a link to an example of a screen I captured and then annotated:
