I saw you posted your inquiry in the Water Cooler- I answered in the WioyM thread, but here it is again.
Hit the "prt scr" button - should be by your number pad/right section of keyboard. Open a graphics editor like "Paint" -should come standard in all Windows operating systems. Either hit "ctrl", plus "v", or hit the "paste" button by the "file" tab. When you save "Save as", make sure you change the file type to "JPEG" to reduce size. Name, and store it in a convenient place for retrieval. Later, simply choose the "attach" option on any email opened, and find the image.
If you have the "fn" key on your keyboard,make sure to press it simultaneously with the "prt scr" button, otherwise you won't capture the image.
