In the game, F2 does a screenshot. (and shift + F2 makes a vast ~1Gb .tga in old versions)

The resultant images are saved in C:/users/"yourname"/appdata/roaming/.minecraft/screenshots

If /appdata/ is hidden, enter %.minecraft% into the startbar, or select the option to show hidden files in folder options.

When you start to write your instructable, you will get the option to upload files.

If you win 7 user find snipping tool and use it.

Hit the Print Screen button on your keyboard. This takes a screen shot of the screen and copies it to the clip board. Now Alt + Tab out of the game and open MS paint or other image editing software of your choice and hit Ctrl + C to copy the image. Save it as a .jpg file and you can upload the image to an instructable.

(It's Control + V to paste into the image program).
