I-JPG yi-JPEG eqhelekileyo ukusukela ngo-1992, inikezelwa phantsi kwe-.jpg,.jpeg kunye ne-.jfif izithuba ezifanayo, kwaye emva kweminyaka emithathu ihlala i-format esetyenziswa ziikhamera ezininzi kunye ne-web sites ezininzi zomfanekiso.

Ingaba uguqulelo JPG ukuya ku ICO lugcina ukubonakala ngaphaya?
