This is excellent!
I was deceived because I was looking only at the available Debian packages. The currently available version only allows to convert from pdb -> jpg.
The maintainers of this package have done a great job, and I do like the command line tool better than any graphic pilot package.
It is also striking that since I convert the pictures manually to 320x320 resolution, image size is smaller and downloading is much faster as compared to the Windoze Pilot Desktop. It is hardly believable, but I think that the Windoze version did not resize the picture, but sent the entire thing to the Palm. But ahhhh.... that is common practice for Windoze... it should be easy, non configurable and speed or memory use is not an issue at all. If your program is too slow, upgrade your hardware, do not try to make you program better!.
Thanks again for helping me out.
