hOrniThe “G” stands for “Graphics”. Why would anybody pronounce it “jif”?
The P in JPEG stands for photographic so I guess we shall pronounce it “jayfeg” based on that logic.

Descriptive linguistic opinion: both the hard and soft G pronunciations are used, with the hard G being more common, but I like the soft G and use it myself.
But if the creator of jpeg came out tomorrow and said "it’s actually supposed to be pronounced “jayfeg”, would anyone change how they say it? I highly doubt it.
