The first thing you should do when downloading software is to read the README and INSTALL files. I checked for you, and INSTALL is in doc, so read doc/INSTALL.
I don't follow you. There was no doc/install in the netpbm compiled binaries I downloaded from the gallery site. There was a readme and I read it.
Of course, cause they're not in your $PATH.
What isn't in my path? Which? Whereis? NetPBM?
[$ which which
$ which whereis
If I knew what should be in my path to find 'them', I guess I wouldn't have been trying to find them with which and whereis.
This might be too simple for you, but I use this program:
(mthumbnail) to make thumbnails. It uses ImageMagick (already installed) to make them.
Thanks for the pointer. My concern is getting thumbnails made automatically (or at least, without my intervention) for users placing images into a club gallery.
Thanks for your thoughts.
