Hi Herbie,
I think that is too strong of a statement against jpegs. Whether jpeg
is suitable or not depends on the analysis being done and the amount of
compression being applied. The original imaging method is often
responsible for gross distortions and the jpeg compression artifacts are
minor in comparison.
For example I used to work for a CT manufacturer. Radiologists
routinely created images with resolution far beyond what the physical
resolution of our machine justified. A little jpeg compression on top
of this makes no difference.
Jpeg has taken over imaging, for better or worse. (If only jpeg2000 had
taken hold before the consumer digital cameras, alas.) ImageJ should
support jpegs as well as it supports tiffs.
