I love it. Keep it up! Maybe it is a 50% reduction in file size, not a
50% reduction in real estate. Maybe not. And you do know what happens
every time you save a *.jpg file, right? It just keeps on compressing
itself.

I noticed that many of the image programs offer a compression option when
saving .jpg files. You can select anything from "lots" of compression for
smaller files and low quality or "no" compression for high quality but
bigger file sizes. Are you suggesting that they become compressed anyway,
by default?

If you use Paint Shop Pro and save an image in its native format
(*.pspimage), it is "lossless". I bet Photo Shop and Elements are the same
way regarding their native format.

It is also correct that every time you save an image in the jpeg format,
even without compression, there is some amount of information lost.

There is supposedly a "lossless" jpeg format that I've never played with but
have read it's not completely as advertised.
