The First Image Published on the Web
rcastro0 writes "A charming picture of "Les Horribles Cernettes" was the first ever to grace a web browser window, according to Silvano de Gennaro from the CERN Music Club site. He writes 'Back in 1992, after their show at the CERN Hardronic Festival, my colleague Tim Berners-Lee asked me for a few scanned photos of "the CERN girls" to publish them on some sort of information system he had just invented, called the "World Wide Web".' As an aside, the all-girl rock band is still singing about "colliders, quarks, microwaves, antiprotons and the Internet.""

The first web browser was on NEXTSTEP (now called OS X), which supported jpeg natively. If you support images at all using NEXSTEP's built-in objects (I assume it was NSImage then as now), you automatically get jpeg support. You'd have to pretty much have some reason not to show jpegs if you weren't going to include support for them, unlike Netscape (nee Mosaic) where the developers had to add in all the formats you wanted individually (graphics format support wasn't all that advanced back then under most Unices, as Rasterman wouldn't start on imlib for about 4-5 years).
