And it happens I have a photo taken in Kakadu right here! (the croc at the
bottom).
Thanks for the info on this - I tried the bathroom humour national park
professor and his students version (thanks for the link) and it was
horrendously slow - over a minute to save a 28MB file. But it did give 2:1
reduction lossless as you suggested, which is impressive in itself. I
checked and it was indeed lossless - not a single pixel different.
I also checked pixel variations between JPEG and J2K for various
compressions, and found it hard to draw any conclusions - I wasn't bowled
over by the improvement of J2K over ordinary jpeg, and the speed difference
is astoundingly in favour of jpeg. I was interested in all this because my
disks are finally full and I can't keep backing up onto the other disk, so
I have to save to CD. But it would take me a long time to resave all those
files using this plugin. I will try the commercial versions and see if the
speed is good enough on my system.
Thanks for all the good info,
Julian
