On the subject of an Images news group: I think that if people limit the size of their images to 50 kbytes to start out with, this will encourage people to work on better and better image compression techniques. How about Hi-res luminence and low res chroma? I wouldn't mind seeing images posted in any format as long as a converter is available. This ties in with the paragraph above. To put this entire discussion into perspective, lets do a litle analysis of comp.graphics traffic. Over the past few weeks here's a break down of the larger messages transmitted on comp.graphics: 14,872 bytes 649 lines: X11R3 Color data base. Paul Raveling from USC Information Sciences Institute Oct 20. 10,948 bytes 215 lines: Image file format discussion Allen Braunsdorf from Purdue Oct 20. 150,136 bytes 2507 lines: Seisomograms of SF earthquake. Ken Schmahl of Sun Microsystems. Sent on Oct 23. 15,701 bytes 372 lines: GPLOT CGM interpreter. Phil Andrews at Pittsburg Supercomouting Center. Oct 27 40,328 bytes 671 lines: Here's a GIF image fall.gif Paul Haeberli at Silicon Graphics Oct 31. 14,654 bytes 366 lines: INTERACT'90 Conference Announcement. R. Winder at ucl. Nov 3. 47,022 bytes 777 lines: Here's a GIF image domain.gif Paul Haeberli at Silicon Graphics Nov 7. 19,455 bytes 359 lines: Raytracing News Eric Haines at 3D/Eye Inc. 28 Oct. Notice that one message from Ken Schmahl was three times the size of one of my GIF images and also please note that the size of the accumulated discussion about transmitting images over comp.graphics exceeds 45k bytes. 45,253 bytes 997 lines: 33 messages discussing how to handle images on comp.graphics. I don't see any problem with any of these postings listed above. Its interesting to compare traffic on comp.graphics to net.sources.unix: comp.sources.unix: ~317000 bytes per day. comp.graphics: ~37836 bytes per day. I'd love to see 7 images from the computer graphics community every week. If there was 1 image transmitted every day this would increase the volume from 38 Kbytes up to 90 Kbytes. There are several other news groups that easily exceed this volume. Even at a miserable 1200 baud this would take a total of 12 minutes and 30 seconds to transmit. Now tell me that horror story again about your 8 Hour network feeds . . . . . . . One kind of comment really upsets me - its the one that implies if its an image - it has no value on the net. Are these people blind? I would love it if people would share the results of their research on the net. How about also trading enviroment maps and "interesting" periodic texture maps? A name with comp.binaries.images is fine with me!! 415-962-3665 Paul Haeberli paul@sgi.com

Exactly the same could be done here. Also, leaf sites could sys-file it out if they don't want it, and backbone(-ish) sites could simply rebatch forward and not store locally other than for the duration of the transmission.

Does this mean that you'll be moderating the newsgroup and rejecting
all postings greater than this size?
-Its interesting to compare traffic on comp.graphics to net.sources.unix:
-
- comp.sources.unix: ~317000 bytes per day.
- comp.graphics: ~37836 bytes per day.
It's more interesting to look at applicability; given the history of the
net, a majority of the people on the net will have more use for unix
sources than for pictures; which comp.graphics isn't about.
People will use whatever bandwith is available...and then some. If it's
not moderated it will be abused. So who's going to do it?
