Graphics Interchange Format. GIFs are image files that are compressed to reduce transfer time. The proper pronounciation of the acronym is a soft "g" sound: like JIF.
The creators of
the format, Bob Berry & Steve Wilhite, claim that this soft "g" sound is used. At some point
one of them said, "Choosy programmers choose GIF," a play on the
peanut butter commercials where "Choosy moms choose Jif." It can also use multiple images for animated effects (animated GIFs).
