Libjpeg 9 improves lossless JPEG compression

The Independent JPEG Group (IJG) at the German Institute for Applied Informatics (InfAI) has released a new version of the libjpeg library. The developers say it can compress photos in JPEG format in a lossless way and, apparently, libjpeg 9 outputs lossless JPEG files that are smaller than the equivalent PNG file of the same image

Better than PNG AND lossless, nice! But what about alpha channel/transparency? Hmmmm...!  :-\

Crap! Why, if i want to modify my post, the subject is offered as a textbox, but cannot be changed/corrected? It's read only! :( I missed a "w" at "new" in my subject :( Sorry guys but you got the idea. :)

Browser issue? I'm used to be able to edit the entire message, including the subject :-\
Edit: Hm, this might be a forum permission issue, can't change the subject of this message either :o

Do you think is this going to be implementable in regular .jpg .jpeg files?

if so, wonder how long it'll take...
