What do you do with sprite sheets?

[Dazz]

spritesheets are not intended for wanting just one sprite. They are for loading into games. Once loaded, the code will animate this sheet by displaying each frame in a flip-book manner using parameters specified by the programmer.

You interoperated the question wrong. He asked what if you want one image out of the a sprite sheet, and not to use the whole sheet. Not if you want to make a sprite sheet out of one sprite.
