If so, open the file and right click on it. Does "Save Picture As" show up
as an option? If so, you are in luck, and can save it as a .jpg, hopefully.
If not, copy the image and paste it into Paint. To do this, click Edit -
Paste on the Paint menu. (Paint is in Accessories, within Programs, on your
Start Menu.
Then, you can save it (File - Save As) as a wide variety of formats,
including JPG.
