For my screenshots i used a program. I start the program up prior to starting FS9.
Once i start flying i just press the Print Screen key and it automatically saves the photo to my desktop without having to pause my flight.
Like stated above, i needed to then change the file type to JPEG. (see reply #2)
I did this by importing the desktop photo to MSPAint and then saving it in a JPEG file in lieu of the standard bmp file.
The result of changing it to a JPEG file is shown in reply # 3
