Well, first you have to enable screenshots, to do this go to: (by default) "C:\Program Files\Bethesda Softworks\Morrowind" and find the file named "Morrowind.ini", now right-click and select "Open With...", and a window with a list of programs should appear, first make sure the
"Always use the selected programs to open this kind of file" check box is empty (always make sure its
not checked), now find and open with "Notepad". Then find the entry "Screen Shot Enable=0" and change the 0 to 1 (then it will be "Screen Shot Enable=1"), then close and save, also note all screenshots will appear in the same folder as the "Morrowind.ini" file. So next time you want to take a screenshot ingame, press the "Print Screen" key on your keyboard.
Hope that helps.
Now here are some of mine that I took:
