Quote:
Being able to copy, modify, and share image files on the Internet is something we take for granted now, but the standards body in charge of JPEG is looking to change that.

For several months, the JPEG Committee has been considering a DRM scheme for its wildly popular image format. While a DRM extension already exists for JPEG 2000—a version used for medical imaging and other professional cases—the committee is now thinking of adding DRM more broadly. The Electronic Frontier Foundation wrote about this issue this week, and presented its case against DRM to the JPEG standards body.

Apart from if you like decent photos. It's great for graphic content however.

The FLIF format might come to something, however. Once it's possible to licence it and so on.

:lol: Bollocks. We're talking about JPEGs here

JPEG and PNG are both crap at photos, but JPG is smaller

The thing is, JPEG is good enough. At least if you don't set the compression too high.

PNG supports millions of colours, there’s a subset which has a limit of 256 colours should that be all you need. Historically, PNG was created as an alternative for GIF which was subject to patent licensing (now expired). It also supports animations, though to date, I don’t think anyone has seen an animated PNG.

PNG isn’t lossy, so data in = data out. JPEG is lossy, so data in != data out. The decompressed image is not identical to the original and there is detail and colour information lost. PNG loses out to JPEG as the latter can carry colour profiling data, while the former can’t. PNG also can have 256 level of grey scale masking, which is useful.
